A bag contains 5 blue marbles, 3 red marbles, and 2 yellow marbles. You select a marble at random. What is P(yellow)
A: 2/8
B:4/5
C:1/5
And if you have the answers to the rest tell me
I will have the answers momentarily, please wait.
There are a total of 10 marbles. Out of those 2 are yellow. So, the probability of picking a yellow marble is 2/10, or 1/5 simplified.
I'm sorry, I could not find the rest of the answers, but this is the correct answer to this question.
@helper thank you
Your welcome.
To find the probability of selecting a yellow marble, we need to determine the number of favorable outcomes (yellow marbles) and the total number of outcomes (total marbles in the bag).
In this case, the number of yellow marbles is 2, and the total number of marbles is 5 + 3 + 2 = 10.
Therefore, the probability of selecting a yellow marble can be calculated as:
P(yellow) = Number of yellow marbles / Total number of marbles
= 2 / 10
= 1/5
So, the correct answer is C: 1/5.
As for the rest of the answers, the probability of selecting a blue marble can be calculated as:
P(blue) = Number of blue marbles / Total number of marbles
= 5 / 10
= 1/2
So, the probability of selecting a blue marble is 1/2.
The probability of selecting a red marble can be calculated as:
P(red) = Number of red marbles / Total number of marbles
= 3 / 10
And for the other options:
A: 2/8 = 1/4, which is not the correct probability for selecting a yellow marble.
B: 4/5 is not even one of the given options and is not the correct probability for selecting a yellow marble.
