Question
**Problem 8: Probability Distribution of Free Throws**

A basketball player has a free throw shooting percentage of 80%. He was fouled while attempting a three-point shot and will be shooting 3 free throws. Make a probability distribution for the number of shots he makes.

a. **List all possible outcomes:**

   - Possible outcomes for each shot could be: Made (M) or Missed (X).
   - Combined outcomes for 3 shots could be:
     - MMM
     - MMX
     - MXM
     - MXX
     - XMM
     - XMX
     - XXM
     - XXX

b. **List all events; in this case, what are the possible numbers of shots made?**

   - Possible numbers of successful shots: 0, 1, 2, or 3.

c. **Find the probability of each event and display the probabilities in the table:**

   | Event | Probability of Event |
   |-------|----------------------|
   | Makes 0 shots | P(Made=0)     |
   | Makes 1 shot  | P(Made=1)     |
   | Makes 2 shots | P(Made=2)     |
   | Makes 3 shots | P(Made=3)     |
   | **Total**     | **1.0**       |

**Note:** The probabilities for each entry in the table depend on calculating the number of ways each event can occur multiplied by the probability of each outcome, based on the 80% success rate per shot and 20% failure rate.
