Hi
p(rain) = .25, n = 4
P(x >= 2) = 1 - binomcdf(4, .25, 1) = .2617  (Recommend Using TI)
Or P(x >= 2) = P(2) + P(3) + P(4)
Using 
{{{P (x)= highlight_green(nCx)(p^x)(q)^(n-x) }}} 
p and q are the probabilities of success and failure respectively. 
In this case p= .25, q = .75,  n=4
{{{nCx = (n!)/x!(n - x)!)}}}
