Answer: $108
Step-by-step explanation:
3% = 0.03
1800 x 0.03 x 2 = 108
Using the binomial distribution, it is found that there is a 0.125 = 12.5% probability that the team goes to the championship.
<h3>What is the binomial distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- His team has a p = 0.5 probability of winning each game.
- The team plays 3 games, hence n = 3.
The team moves to the championship if they win all three games, hence the probability is P(X = 3), given as follows:
0.125 = 12.5% probability that the team goes to the championship.

This problem states that there are 5 trophies and the problem requires to determine the number of ways Naomi can line up her trophies. In this case, the formula using counting is 5 * 4 * 3 * 2 * 1. there is a decreasing trend as the number of trophies chosen to line up next is decreased by one each time. The answer is 120 ways.
