Question

Jon's closet has 3 black shirts, 8 blue shirts, 6 black pants and 7 blue pants. He wants to determine the probability of selecting a black piece of clothing or a shirt from his closet. He solves the probability this way. P(black piece of clothing or a shirt)=P(black piece of clothing)+P(shirt) = 9/24+11/24=20/24=5/6 did he solve it correctly? Please explain your reasoning.

Answer 1

Answer:no

so, there is no need for 9/24+11/24=20/24=5/6 because we are looking for only the black piece

Explanation:

p(black piece of clothing or a shirt)=p(black piece of shirt)+p(black piece of clothing)

=6+3/24

=9/24

3/8 is the probability of picking a black piece of clothing or a shirt
