If a person tosses a coin 23 times, how many ways can he get 11 heads

Tossing a coin is a binomial experiment.

Now lets say there are 'n' repeated trials to get heads. Each of the trials can result in either a head or a tail.

All of these trials are independent since the result of one trial does not affect the result of the next trial.

Now, for 'n' repeated trials the total number of successes is given by

where 'r' denotes the number of successful results.

In our case and ,

Substituting the values we get,

Therefore, there are 1352078 ways to get heads if a person tosses a coin 23 times.

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
