Answer 1

35:100*14=4.9%из 10 что ему попадётся билет который он учил

Answer 2

Probability of drawing a learned ticket

To find the probability that Andrey will draw a ticket that he has learned, we need to know the total number of tickets and the number of tickets he has learned.

According to the information provided, there are 35 tickets in total and Andrey has learned 14 of them.

The probability of drawing a learned ticket can be calculated using the formula:

Probability = (Number of favorable outcomes) / (Total number of possible outcomes)

In this case, the number of favorable outcomes is the number of tickets Andrey has learned, which is 14. The total number of possible outcomes is the total number of tickets, which is 35.

Therefore, the probability that Andrey will draw a learned ticket is:

Probability = 14 / 35

Simplifying the fraction, we get:

Probability = 2 / 5

So, the probability that Andrey will draw a ticket he has learned is 2/5 or 0.4.
