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?
Expected number of successful slap shots = Probability of success x Number of attempts
Probability of success = 1/5
Number of attempts = 120
Expected number of successful slap shots = (1/5) x 120
= 24
Therefore, you would expect her to make 24 successful slap shots after 120 attempts.
