- Homework Statement
- 45% of the population is said to for a certain political block A at an election. 10 people are sampled.

a) Whats the prob that 5 of them vote block A?

b) What the prob that none of them vote block A?

- Relevant Equations
- P(A and B) = P(A) * P(B)

P(Not B) = 1 - P(B)

A) P(A and B) = 0.45 * 5/10

B P(Not B) = 1 - ( 0.45 * 5/10)

Is it like this?

B P(Not B) = 1 - ( 0.45 * 5/10)

Is it like this?
