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.
To find the expected number of successful slap shots, we simply multiply the probability of success (1/5) by the number of attempts (120):
Expected number of successful slap shots = (1/5) x 120 = 24
Therefore, we would expect the hockey player to make 24 successful slap shots out of 120 attempts.
To calculate the number of successful slap shots you would expect the hockey player to make after 120 attempts, you can use the formula for expected value.
Expected Value = Number of Attempts × Probability of Success
For this case, the number of attempts is 120 and the probability of success is 1/5.
Expected Value = 120 × 1/5
Expected Value = 24
Therefore, you would expect the hockey player to make approximately 24 successful slap shots after 120 attempts.
