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

total number of outfits = 12
total number of outfits with blue skirt = 3x1x2 = 6

prob of outfit with blue skirt = 6/12 = 12
prob of outfit without blue skirt = 1 - 1/2 = 1/2
