+525 A box contains 4 black shirts, 8 blue shirts, 4 black pants, and 10 blue pants. Determine the probability of randomly selecting a blue piece of clothing or a pair of pants. Use P(A or B) = P(A) + P(B) - P(A and B) to explain your answer.
Answer:
+130110 P (Blue Clothing or a Pair of Pants ) = ????
P( Blue Clothing) = 18/26
P( Pair of Pants) = (14/26)
P( Blue Pair of Pants) = 10/26
So
Probability (Blue Clothing or a Pair of Pants) = P(Blue Clothing) + P (Pair of Pants) - P(Blue Pair of Pants) =
18/26 + 14/26 - 10/26 =
22/26 =
11/13
