Question

Подбросили красную, синию и жёлтую монетки. Какова вероятность, что жёлтая выпадет орлом, а красная и синия решкой? ​

Answer 1

Ответ:

1/8

Пошаговое объяснение:

Вероятность что желтая орлом - 1/2

Красная решкой -1/2

Синяя решкой 1/2

Одновременно красная и синяя решкой - 1/2*1/2=1/4

Одновременно еще желтая орлом - 1/4*1/2=1/8.

Answer 2

Probability of Yellow coin landing on heads and Red and Blue coins landing on tails

To calculate the probability of the yellow coin landing on heads and the red and blue coins landing on tails, we need to consider the total number of possible outcomes and the number of favorable outcomes.

Let's assume that each coin has two sides: heads (H) and tails (T). Since there are three coins, each with two possible outcomes, the total number of possible outcomes is 2^3 = 8.

Out of these 8 possible outcomes, only one outcome satisfies the condition where the yellow coin lands on heads (H) and the red and blue coins land on tails (T). Therefore, the number of favorable outcomes is 1.

The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. In this case, the probability is:

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

Probability = 1 / 8

Therefore, the probability that the yellow coin lands on heads and the red and blue coins land on tails is 1/8.
