Question

A coin is tossed 14 times. What is the
probability of getting heads exactly 5 times?

Answer 1

7

Split the amount as there is only 2 sides to a coin

Answer 2

A coin is tossed 14 times. so, the probability of getting heads exactly 5 times is 0.122.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

A coin is tossed 14 times. we want to find the probability of getting heads exactly 5 times.

Assuming the coin is fair

so, the probability of getting head P(H) = 1/2

the probability of getting tail P(T) = 1/2

$C(14, 5) (\dfrac{1}{2} )^{14}\\\\= 0.122\\\\C(14, 5) = \dfrac{14!}{9!5!}$
