A shipment of grapefruits arrived with the following characteristics. Define these events: P = pink, NS = seedless, W = white, and S = seeds

10% pink and seedless  –> P(P and NS) = 0.1 

20% white and seedless –> P(W and NS) = 0.2

30% pink and seeds –> P(P and S) = 0.3

40% white and seeds –> P(W and S) = 0.4.

What is the probability that a randomly selected grapefruit is pink OR seedless? P(P or NS) = ?
