There are some examples which are shown below for the same:-

Question 1:- A coin is tossed three times. Find the probability of tossing heads exactly two times.

Solution:- Given A coin is tossed three times.

To find: - Probability of tossing heads exactly two times.

There are eight possible combinations:-

HHH, THH, HTH, HHT, THT, TTH, HTT, TTT

In above example, THH, HHT, and HTH are the three combinations of tossing heads exactly two times.

Hence the Probability of tossing heads exactly two times: - 3/8.

Question 2:- A coin is tossed three times. Find the probability of tossing tails exactly two times.

Solution:- Given A coin is tossed three times.

To find: - Probability of tossing tails exactly two times.

There are eight possible combinations:-

HHH, THH, HTH, HHT, THT, TTH, HTT, TTT

In above example, TTH, HTT, and THT are the three combinations of tossing heads exactly two times.

Hence the Probability of tossing tails exactly two times: - 3/8.
