Question

If you flip a coin 10 times, what is the best prediction possible for the number of times it will land on tails?

Answer 1

5

Explanation:

Probability of land a tail when the coin is tossed once is 1/2 because a coin has two sides and contains one head

Then when it is tossed 10 times, the no of time a tail appears is. 1/2 * 10 =5

Answer 2

5

Explanation:

The probability of tails is 1/2, so the expected value is (1/2) (10) = 5.
