Question

A shipment of grapefruit arrived containing the following proportions of types: 10% pink seedless, 20% white seedless, 30% pink with seeds, and 40% white with seeds. A grapefruit is selected random from the shipment. Find the probability that it is pink or seedless.

Answer 1

Answer:

60%

Step-by-step explanation:

The probability that a grapefruit is pink OR seedless is given by the sum of the probabilities of the grapefruit being pink with seeds, pink and seedless or seedless and not pink:

$P(P \cup S) = 10\% +30\%+20\%\\P(P \cup S) = 60\%$

The probability that a randomly selected grapefruit is pink or seedless is 60%.
