Question

Rashida has 3 blouses: red, white, and pink. She has 2 skirts: blue and black. She has 2 pairs of shoes: red and white. what is the probability that Rashida selects an outfit at random that does not include a blue skirt? Write the probability as a percent.

Answer 1

50%

Explanation:

If Rashida selects an outfit at random that does not include a blue skirt, then she must select black skirt.

She can select one blouse from given 3 and one shoes from given 2. Hence she has

`3\cdot 2=6` favorable outcomes of wearing.

At all she has

`3\cdot 2\cdot 2=12` possible outcomes.

Thus, the probability is

`Pr=(6)/(12)=(1)/(2).`

In percent that is 50%.
