Answer 3

Calculating the Probability of Drawing a Learned Ticket

To calculate the probability of Serj getting a learned ticket, we can use the following formula:

Probability = (Number of learned tickets) / (Total number of tickets)

Given that there are 40 tickets in total and Serj has not learned 8 of them, the number of learned tickets would be 40 - 8 = 32.

Applying the Formula

Using the formula, the probability of Serj getting a learned ticket is:

Probability = 32 / 40

Calculating the Probability

Calculating the probability: Probability = 32 / 40 = 0.8

So, the probability of Serj getting a learned ticket is 0.8 or 80%.
