Question

A​ one-week study revealed that​ 60% of a warehouse​ store's customers are women and that​ 30% of women customers spend at least​ $250 on a single visit to the store. Find the probability that a randomly chosen customer will be a woman who spends at least​ $250.

Answer 1

Answer: The probability of a randomly chosen customer to be a woman who spends at least $250 is 0.18 or 18%

Explanation:

60% of the customers are women, and 30% of the women spend at least $250.

We want to find the probability for a randomly selected customer to be a woman that spends at least $250

first, the probability of a random customer to be a woman is 60% or 0.6 in decimal form.

And 30% of those 60% spend at least $250, so the probability the product of those two, this is:

P = 0.6*0.3 = 0.18

So the probability of a randomly chosen customer to be a woman who spends at least $250 is 0.18 or 18%
