Question :In a binomial distribution for p=.48, q=1-p=.52 find the population size n1 so that P(X>=3)=.95
My solution :
P(X>=3)=.95
can be rewrite as
P(X=0)+P(X=1)+P(X=2)=.05 ------------------------------------------ eq(1)
but i am un able to solve the above equation for n1,
Is there any way to solve the equation (1) or is there any alternate solution?

hi,
trial and error? There are only a few possible choices for n.
