Use the binomial orobability formula to find the probability(to 5 deciminal places) that:

a) he gets exactly 2 questions correct.

b)he gets no questions correct.

c) he gets at least 1 question correct(use the information from part (b) to answer this part.

d) he gets at least 9 questions correct.

e) Without using the binomial probability formula, determine the probability that he gets exactly 2 questions correct.

f) Compare your answers to parts (a) and (f). If they are not the same, explain why.

Is there a math wiz out there, that could possibly help me with this problem, or try to walk me through it,I would really appreciate it, Thanks Toni
