Question

в коробке 19 синих шаров, 12 красных и 4 желтых. Найдите вероятность того, что извлеченный наугад шар окажеться синим

Answer 1

вычисляем по формуле Р(А)= N(A)/N , где N(А) - интересующие события (синий шар), N- общее число событий, значит
Р(А)=19/(19+12+4)= 19/35, это приблизительно 54 %

Answer 2

Вероятность извлечения синего шара равна 54 процента

Answer 3

Calculating the Probability of Drawing a Blue Ball

To find the probability of drawing a blue ball from the box, we can use the formula for probability:

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

In this case, the number of favorable outcomes is the number of blue balls, and the total number of outcomes is the total number of balls in the box.

Given that there are 19 blue balls, 12 red balls, and 4 yellow balls, the total number of balls in the box is 19 + 12 + 4 = 35.

Using this information, we can calculate the probability of drawing a blue ball.

Calculation

Probability of drawing a blue ball = (Number of blue balls) / (Total number of balls) Probability of drawing a blue ball = 19 / 35 Probability of drawing a blue ball ≈ 0.5429

So, the probability of drawing a blue ball from the box is approximately 0.5429.
