You can put this solution on YOUR website! According to calculated survey 65% Nig. Women support a woman for president. Let x bethe no. Of women out of random sample of n=25 who support women president.
Binomial Problem with n = 25 and p(vote for woman) = 0.6
-----
Using a TI-84 I found the following::
--------
Find A. P(x >= 22) = 1 - binomcdf(25,0.65,21) = 1-0.99032 = 0.0097
----------------
B. P(x=8) = 25C8*(0.65)^8*0.35^17 = binompdf(25,0.65,8) = 0.000612..
Cheers,
