A basketball player has a free throw success rate of 75%. If he takes 20 free throws, how many successful throws can be expected? (2019)

Step 1: Understand that the player's success rate is 75%. This means he makes 75 out of every 100 free throws.
Step 2: Convert the success rate from a percentage to a decimal. 75% as a decimal is 0.75.
Step 3: Determine how many free throws the player will take. In this case, he will take 20 free throws.
Step 4: Calculate the expected number of successful throws by multiplying the success rate (0.75) by the number of free throws (20).
Step 5: Perform the multiplication: 0.75 * 20 = 15.
Step 6: Conclude that the expected number of successful throws is 15.
