You can put this solution on YOUR website! Five out of 50 people called to give money to a charity actually agrees to give money. Based on this percentage,
Binomial Problem with n = 25 ; p(gave) = 1/10
------------------------------------------------
what is the probability that out of the next 25 people called:
---------------------
a. At least two agree to give money?
Ans:: 1 - binomcdf(25,0.1,1) = 0.7288
-------------------------------------
b. At most 5 agree to give money?
Ans: binomcdf(25,0.1,5) = 0.9666
------------------------------------------
c. More than 3 agree to give money?
Ans: 1 - binomcdf(25,0.1,3) = 0.7636
