<PRE><B>Question 236927</B>
What is the probability that it will rain 2 of the next 10 days when the probability of rain is 90%? Show the formula and your calculations.
------------------------------
It&#39;s binomial with n = 10, p = 0.9, x = 2
-----------------------------------------------
P(x=2) = 10C2(0.9)^2(0.1)^8 = 0.0000003645
