Answer #1

P(A)=P(your car will start)=0.50

P(B)=P(neighbours car will start)=0.80

Both events are independent of each other

A) neither will start

P(neither will start)

Probability that neither will start is 0.1

B) both cars will start

Probability that both car will star is 0.4

C) either both car will start or neither car will start

D) exactly one of the car will start
