Question: If A, B, and C are mutually exclusive events, is it possi ble for P(A) = 0.3, P(B) = 0.4, and P(C)=0.5? Why or why

If A, B, and C are mutually exclusive events, is it possi ble for P(A) = 0.3, P(B) = 0.4, and P(C)=0.5? Why or why not? roundness conforms Tool 1 yes surface finish yes 200 conforms 4 Tool 2 yes surface finish conforms yes 145 Do 8 I 2 roundness conforms 4 6

(a) If a shaft is selected at random, what is the probability that the shaft conforms to surface finish requirements or to roundness requirements or is from Tool 1?

(b) If a shaft is selected at random, what is the probability that the shaft conforms to surface finish requirements or does not conform to roundness requirements or is from Tool 2?

(c) If a shaft is selected at random, what is the probability that the shaft conforms to both surface finish and roundness requirements or the shaft is from Tool 2?

(d) If a shaft is selected at random, what is the probability that the shaft conforms to surface finish requirements or the shaft is from Tool 2?
