Question 325592: A can solve 90% of the problems while B can solve 80% of problems in statistics. A problem is selected at random and what is the probability that atleast one of them will solve it? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! A can solve 90% of the problems while B can solve 80% of problems in statistics. A problem is selected at random and what is the probability that atleast one of them will solve it?
----------------
P(at least one) = 1 - P(none)
-----------------------------------
P(neither can solve the problem) = 0.10*0.20 = 0.02
----
P(at least one can solve the problem) = 1 - 0.02 = 0.98
