Question

If you flip a coin 4 times, what is the best prediction possible for the number of times it will land on tails? 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

Probability of getting tail (Number times a coins flip = 4 times) = 2

Probability of getting tail (Number times a coins flip = 4 times) = 5

Explanation:

A . Number times a coins flip = 4 times

B . Number times a coins flip = 10 times

Computation:

Probability of getting tail = 1/2

Probability of getting tail (Number times a coins flip = 4 times) = 1/2(4)

Probability of getting tail (Number times a coins flip = 4 times) = 2

Probability of getting tail (Number times a coins flip = 4 times) = 1/2(10)

Probability of getting tail (Number times a coins flip = 4 times) = 5
