The probability of a certain hockey player making a goal after hitting a slap shot is 1/5. How many successful slap shots would you expect her to make after 120 attempts
The expected number of successful slap shots is equal to the probability of making a successful slap shot multiplied by the total number of attempts:
Expected number of successful slap shots = (probability of success) x (total number of attempts)
Expected number of successful slap shots = (1/5) x 120
Expected number of successful slap shots = 24
Therefore, you would expect the hockey player to make 24 successful slap shots after 120 attempts.
