I have a strong feeling that you have a typo, and that you meant to say,
"Assuming we randomly select 12 people. "

These are not multiple choice answers, they are individual questions

a) prob that exactly 5 out of 12 will recognize
= appr 0.0918
prob = C(12,0)(.61)^0 (.39)^12 + C(12,1)(.61)^1 (.39)^11 + ... + C(12,5)(.61)^5 (.39)^7
c) prob = 1 - (answer to b)
d) prob = C(12,0)(.61)^0 (.39)^12
