Question 393749: John and Anita can solve 90% and 70% respectively of statistics problems. If they
try a statistics problem independently, what is the probability that:
(a) both of them solve the problem,
(b) only John solves the problem,
(c) only Anita solves the problem,
(d) neither of them solve the problem,
(e) the problem is solved (or at least one of them solve the problem)
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! John and Anita can solve 90% and 70% respectively of statistics problems. If they
try a statistics problem independently, what is the probability that:
(a) both of them solve the problem,:::0.9*0.7
-----------------------
(b) only John solves the problem,:::0.9*0.3
-----------------------
(c) only Anita solves the problem,:::0.1*0.7
-----------------------------
(d) neither of them solve the problem,:::0.1*0.3
------------------------------
(e) the problem is solved (or at least one of them solve the problem)
1-0.1*0.3
