Answer:
a. The equation for computing Gustin's profit per seminar can be expressed as follows:
Profit = (Commission per new account * Number of new accounts) - Cost per seminar
Profit = ($5000 * 0.01 * 25) - $3500
Profit = $125 - $3500
Profit = -$3375
Therefore, Gustin is expected to lose $3375 per seminar.
b. The number of new accounts opened is a binomial random variable, as it has a fixed number of trials (25 individuals attending the seminar), and each trial (individual) has a binary outcome (either opening a new account or not).
