Question

Paul has 15 T-shirts. The information shows the colours of his T-shirts. He takes one of his blue T-shirts at random. What is the probability that the T-shirt is light blue? 5 black 3 white 3 red 2 dark blue 1 light blue 1 yellow

Answer 1

1/3

Explanation:

In math, to find the probability of an event we need to take the total amount of favorable outcomes and divide this number between the total amount of possible outcomes.

In this case Paul has 15 T-shirts and he takes one of his blue T-shirts at random. We can see that he has a total of 3 blue shirts, thus, the total amount of possible outcomes is 3.

Now, we need to find the probability that the T-shirt is light blue, he only has 1 light blue t-shirt so the number of favorable outcomes is 1.

If we divide the number of favorable outcomes between the number of possible outcomes we have
`(1)/(3)`. Thus, the probability that the T-shirt is light blue is 1/3
