you and 50 coworkers decide to play a game that consists of flipping a coin once for each coworker. If the flip coin for the particular coworker results in a head, you have to pay them $1. If it results in tail, neither party has to pay anything. Given the information provided above, and assuming that the coin you are using is a far coin (i.e. the probability of getting a head or a is equal to 0.5) use Microsoft excel, as your graphing calculator, or the binomial probability formula to calculate the probibilities of the following events. Event A: The probability that you will have to oay out exactly $20. (In other words, the probability that 20 of the flips of the coin will result in heads.) Event B: The probability that you will not have to pay anyone anything. (In other words, the probability that none of the flips of the coin will result in heads.

the probability is 0
