Question

Janice bought 4 shirts that are red green white and yellow and 3 pairs of pants that are black, light blue and dark blue use an organized list to determine the probability that Janice wears a white shirt and blue pants if she randomly chooses her outfit from her new clothes

Answer 1

16.7%

Explanation:

The first thing is to mention that they are two independent events, therefore the final probability is the multiplication of the two.

First event, select shirt. In total there are 4 and you must choose one of them, therefore the probability is:

1/4

Second event, select the pants. In total there are 3 and you must choose one of them, but there are two blue types, therefore any of the two is worth what means that the probability is:

2/3

The final probability:

P = 1/4 * 2/3

P = 0.167

Which means that the probability of choosing a white shirt and a blue pant (light or dark) is 16.7%
