Question

A company knows that 32% of their customers order their product in Black and 26% in White and 22% in Grey.

2 orders are made, Find the probability that at least 1 is Grey.

Answer 1

To find the probability that at least 1 order is Grey, we can use the complement rule, which states that the probability of an event occurring is equal to 1 minus the probability of the event not occurring.

The probability that neither order is Grey is equal to the probability that both orders are not Grey. We can calculate this probability by multiplying the probabilities of both orders not being Grey:

P(both not Grey) = (1 - 0.22) x (1 - 0.22) = 0.64

Therefore, the probability that at least 1 order is Grey is:

P(at least 1 Grey) = 1 - P(both not Grey) = 1 - 0.64 = 0.36

So the probability that at least 1 order is Grey is 0.36, or 36%.
