Answer 1

Problem Analysis

We are given a plate with 15 pastries: 3 with meat, 9 with cabbage, and 3 with cherries. Romа randomly chooses one pastry from the plate. We need to find the probability that he chooses a pastry with cherries.

Solution

To find the probability, we need to determine the total number of possible outcomes and the number of favorable outcomes.

The total number of possible outcomes is the total number of pastries on the plate, which is 15.

The number of favorable outcomes is the number of pastries with cherries, which is 3.

Therefore, the probability that Romа chooses a pastry with cherries is given by:

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

Let's calculate the probability.

Calculation

Number of favorable outcomes = 3

Total number of possible outcomes = 15

Probability = 3 / 15 = 0.2

Therefore, the probability that Romа chooses a pastry with cherries is 0.2.

Conclusion

The probability that Romа chooses a pastry with cherries is 0.2.
