Explanation:

Answer 2

He is expected to win 25% of the time

50 times

Explanation:

If we use fair coins

The probability for one coin landing face up is 0.5

(50% of the time)

Since we need both coins landing face up, we multiply the probabilities

(0.5)*(0.5) = 0.25

(25 % of the time)

This means that

0.25 * 200 times = 50 times
