if there are 4 red, 2 blue, 1 yellow, and 1 green on a spinner, what are the chances of getting a green?
The total number of sections on the spinner is 8 (4 red + 2 blue + 1 yellow + 1 green).
The probability of getting a green is the number of green sections (1) divided by the total number of sections (8).
So, the chances of getting a green are 1/8 or 12.5%.
what are the chances of getting red or blue?
red-7
blue-13
yellow-3
green-15
orange-12
To find the chances of getting red or blue, you need to add up the number of red and blue sections on the spinner, and then divide by the total number of sections.
Total number of red and blue sections = 7 + 13 = 20
Total number of sections on the spinner = 7 + 13 + 3 + 15 + 12 = 50
Chances of getting red or blue = 20/50 = 2/5 = 40%
Therefore, the chances of getting red or blue are 40%.
ok thank you I understand the concept now.
You're welcome! I'm glad I could help you understand the concept. If you have any more questions, feel free to ask.
wait can you explain this one too? a number cube with the numbers 1-6 what is the probability of rolling a number a number greater than 5? Can you also help me understand the probability of dice?
Sure!
A number cube with the numbers 1-6 has 6 sides, one with each number. The chance of rolling a number greater than 5 (i.e., rolling a 6) is 1 out of 6, since there is only one side with a 6 on it.
So, the probability of rolling a number greater than 5 is 1/6 or approximately 16.67%.
For dice, it works very similarly. A standard die has six sides, each with a different number from 1 to 6. The probability of rolling any particular number is 1/6, since there is only one side with that number.
The probability of rolling a certain combination of numbers, such as rolling a total of 7 with two dice, can be a bit more complicated, but the basic principle is the same. You need to count the number of ways you can roll the desired combination, and divide by the total number of possible outcomes.
For example, the probability of rolling a total of 7 with two dice is 6/36 or 1/6, since there are 6 ways to roll a total of 7 (1+6, 2+5, 3+4, 4+3, 5+2, 6+1) out of a total of 36 possible outcomes (6 possible outcomes for each of the two dice).
ok thank you!
You're welcome! If you have any more questions, feel free to ask.
alright, so about the dice, what about this question?: a number cube is rolled 360 times:
1-41
2-54
3-62
4-74
5-33
6-96
Whats the probability of rolling a 2 or a 3?
To find the probability of rolling a 2 or a 3, you need to add up the number of times a 2 or a 3 was rolled, and divide by the total number of rolls (which is 360 in this case).
Number of times a 2 or a 3 was rolled = 54 (number of 2's rolled) + 62 (number of 3's rolled) = 116
Probability of rolling a 2 or a 3 = (Number of times a 2 or 3 was rolled) / (Total number of rolls)
Probability of rolling a 2 or a 3 = 116 / 360
Probability of rolling a 2 or a 3 = 0.3222 (rounded to four decimal places)
So, the probability of rolling a 2 or a 3 is approximately 0.3222 or 32.22%.
Ok, so if i randomly pick marbles out of a bowl and get 6 blue, 4 yellow, 2 red, 3 green, and 5 purple marbles, the probability of getting a yellow is 2/10?
You are correct that there are 2 yellow marbles out of a total of 10 marbles. However, the probability of picking a yellow marble depends on how many marbles you pick out of the bowl.
For example, if you pick one marble out of the bowl, the probability of getting a yellow marble is:
Number of yellow marbles / Total number of marbles = 4 / 20 = 1 / 5
So the probability of getting a yellow marble when picking one marble out of the bowl is 1 out of 5, or 0.2, or 20%.
If you pick multiple marbles out of the bowl, the probabilities can change depending on whether you replace the marble after picking it or not. This concept is known as sampling with or without replacement.
then what would be the probability of getting a marble that isn't yellow?
To find the probability of getting a marble that isn't yellow, you need to add up the number of marbles that are not yellow (which is 6 blue, 2 red, 3 green, and 5 purple) and divide by the total number of marbles (which is 6 + 4 + 2 + 3 + 5 = 20).
So, the probability of getting a marble that isn't yellow is:
Number of marbles that aren't yellow / Total number of marbles
= (6 blue + 2 red + 3 green + 5 purple) / 20
= 16 / 20
= 4 / 5
= 0.8
So, the probability of getting a marble that isn't yellow is 0.8 or 80%.
