Question 87915
The probability that Robin Hood hits a target is 5/6. The probability that Little John hits a target is 1/7. If Robin Hood and Little John each shoot one arrow at the target, what is the probability that they both miss?:
-------------
The events are independent so 
P(A AND B) = [Prob(A)*Prob(B)
Prob(miss AND miss) = (1/6)(6/7) = 1/7
