Question

According to Vinay's model, what is the probability that he will have a male history teacher two years in a row?

1. 3/8
2. (3/8)(2)
3. (3/8)^(2)
4. 3/(8)^(2)​

Answer 1

(3/8)^2 would be your answer.

Since there are 3 male and 5 female, that means there are 3/8 male and 5/8 female. We are talking about male and how many times it would happen in 2 years, so (3/8)^2 would be your answer.

Answer 2

(3/8) ^2

Explanation:

P ( male history teacher) = Number males/ total

= 3/8

Assuming nothing changes in year two

P ( male history teacher year two) = Number males/ total

= 3/8

P( male, male) = 3/8 * 3/8 = (3/8) ^2
