Greg is the lead scorer on his school’s hockey team. He scores a goal 3 out of every 4 attempts. Design a simulation to determine the probability Greg will score a goal on his next attempt.
One possible simulation to determine the probability that Greg will score a goal on his next attempt is to flip a coin where heads represents a successful goal and tails represents an unsuccessful goal. Flip the coin four times and record the results. Calculate the proportion of successful goals (i.e., heads) in the four trials, which will be an estimate of the probability that Greg will score a goal on his next attempt. Repeat the simulation multiple times and take the average proportion of successful goals across all trials for a more accurate estimate of the probability.
short pls :)
Flip a coin four times and record the number of times Greg scores a goal on his next attempt (heads) and the number of times he does not (tails). Calculate the proportion of successful goals in the four trials to estimate the probability that Greg will score a goal on his next attempt. Repeat the simulation multiple times and take the average proportion of successful goals across all trials for a more accurate estimate of the probability.
Julia has a bag with a purple marble, a white marble and an orange marble. She pulls a marble from the bag and then puts it back 3 times.
How many possible outcomes are there for this experiment?
There are 27 possible outcomes for this experiment.
To see why, note that for each of the three times Julia draws a marble, there are three possible outcomes (purple, white, or orange) since she replaces the marble after each draw. Thus, the total number of possible outcomes is 3 x 3 x 3 = 27.
What is the probability of selecting exactly 2 white marbles?
To calculate the probability of selecting exactly 2 white marbles, we need to consider the number of ways in which this can happen and divide by the total number of possible outcomes.
There are three ways in which Julia can select exactly 2 white marbles:
1. White-white-not white
2. White-not white-white
3. Not white-white-white
Each of these outcomes has a probability of (1/3) x (1/3) x (2/3) = 2/27, since there is a 1/3 chance of selecting a white marble on each draw and a 2/3 chance of not selecting a white marble on the remaining draw(s).
Therefore, the total probability of selecting exactly 2 white marbles is the sum of the probabilities of the three possible outcomes:
P(exactly 2 white marbles) = 2/27 + 2/27 + 2/27 = 6/27 = 2/9
So the probability of selecting exactly 2 white marbles is 2/9.
What is the probability of selecting two orange marbles after selecting a purple marble?
Since Julia puts the marble back in after each draw, the probability of selecting an orange marble after selecting a purple marble is the same as the probability of selecting an orange marble on any given draw, which is 1/3.
Therefore, the probability of selecting two orange marbles after selecting a purple marble on three subsequent draws is (1/3) x (1/3) x (1/3) = 1/27.
So the probability of selecting two orange marbles after selecting a purple marble is 1/27.

What is the probability of Lydia rolling pairs of the same number?
The probability of Lydia rolling pairs of the same number depends on the number of sides on the die.
On a standard six-sided die, there are 6 ways to roll pairs of the same number (i.e., 1-1, 2-2, 3-3, 4-4, 5-5, and 6-6) out of 36 possible outcomes. Therefore, the probability of rolling pairs of the same number with a six-sided die is:
P(pairs) = 6/36 = 1/6 = 0.1667 = 16.67%
On other types of dice or number cubes, the probability of rolling pairs of the same number may be different, depending on the number of sides and how they are numbered.
short pls
The probability of rolling pairs of the same number on a standard six-sided die is 1/6 or 16.67%.
What is the probability that at least one number will be a 3?
To find the probability that at least one number will be a 3, we can calculate the probability of rolling two dice and NOT getting a 3 on either die, and then subtract this probability from 1.
The probability of not getting a 3 on a single die is 5/6. Since the rolls of each die are independent, the probability of not getting a 3 on two dice is:
(5/6) x (5/6) = 25/36
Therefore, the probability of getting at least one 3 is:
1 - (25/36) = 11/36
So the probability of getting at least one number that is a 3 is 11/36.
Avery selects chips from a bag without looking at them. The bag has 5 green chips, 3 red chips, and 7 blue chips. What is the probability that he selects a red or blue chip?
a) 1/3
b)7/15
c)2/3
d)14/15
The probability that Avery selects a red or blue chip is equal to the sum of the probabilities of selecting a red chip and selecting a blue chip.
The probability of selecting a red chip is 3/15, since there are 3 red chips out of a total of 15 chips.
The probability of selecting a blue chip is 7/15, since there are 7 blue chips out of a total of 15 chips.
Therefore, the probability of selecting a red or blue chip is:
3/15 + 7/15 = 10/15 = 2/3
So the correct answer is (c) 2/3.
