Question

•. Из 28 костей домино наугад выбира- ют одну кость. Какова вероятностьвыбора кости с суммой очков, рав-ной 10?​

Answer 1

p = m/n,

n = 28,

сколькими способами можно набрать 10 очков

10 = 5 + 5 = 6 + 4

m = 2,

p = 2/28 = 1/14

Answer 2

Probability of Choosing a Domino with a Sum of 10

When choosing a single domino from a set of 28 at random, the probability of selecting a domino with a sum of 10 on its two sides can be calculated.

The probability can be determined by considering the number of favorable outcomes (dominoes with a sum of 10) and the total number of possible outcomes (all 28 dominoes).

The probability of choosing a domino with a sum of 10 is 7/18.

This probability can be calculated using the formula: P = (Number of favorable outcomes) / (Total number of possible outcomes)

In this case, the number of favorable outcomes is 7, and the total number of possible outcomes is 18.

Therefore, the probability of choosing a domino with a sum of 10 is 7/18.
