b.) If 1 egg from each species is incubated,what is the probability that something will hatch?
c.) what's the probability that only 1 willhatch? It is known that 4 out of 5 finch eggs hatch(on the average), 6 out of 7 sparrow eggs hatch, and 11 of 12mallard eggs hatch?

a.) List all possible events 1st
b.) If 1 egg from each species is incubated,what is the probability that something will hatch?
c.) what's the probability that only 1 willhatch?

Explanation / Answer

b) P(something will hatch) = 1-p(nothing will hatch) = 1- (1/5)(1/7)(1/12) c) P(only one) = P(finch) + P(sparrow) + P(mallard) =(4/5)(1/7)(1/12) + (1/5)(6/7)(1/12) + (1/5)(1/7)(11/12)
