Question

A basketball player traditionally makes 85% of her free throws. Suppose she shoots 10 baskets and counts the number she makes. To find the probability that she makes less than 8 baskets, what do we enter into the TI84 calculator?

Please help

Answer 1

To calculate the probability of making less than 8 out of 10 baskets for a player with an 85% free-throw success rate, use the 'binomcdf(10, 0.85, 7)' command on a TI84 calculator to get the cumulative probability.

Step-by-step explanation:

To find the probability that a basketball player who traditionally makes 85% of her free throws makes less than 8 baskets out of 10 attempts, you need to use the cumulative binomial probability function on a TI84 calculator.

This function is known as binomcdf on the TI84 calculator. You will enter the following into the calculator: binomcdf(10, 0.85, 7).

This command calculates the cumulative probability of the player making 0, 1, 2, ..., or 7 baskets, which by extension gives us the probability of making less than 8 baskets.
