Question 934882
The odds against students X solving a statistics problem are 8:6
P(X solves) = 6/14 = 3/7
P(X fails to solve) = 8/14 = 4/7
------------------------------------------
 and odds in favor of a student U solving the problem are 14:16
P(U solves) = 14/30 = 7/15
P(U fails to solve) = 16/30 = 8/15
-------------------------------------------------
.what is the chance that the problem will be solved if they both try independently of each other
Ans; P(solve) = 1 - P(both fail) = 1 - (4/7)(8/15) = 1-(32/105) = 73/105
------------------------------
 and what is the probability that neither solves the problem?
Ans: P(both fail) = (4/7)(8/15) = 32/105
