Question

на клумбе высадили 9 белых 15 красных и 6 жёлтых роз поставил первый цветок Какова вероятность что он будет белого цвета​

Answer 1

Всего цветов 9 + 15 + 6 = 30 цветов

Белых цветов - 9

Тогда вероятность = 9/30 = 3/10

Ответ: 3/10

Answer 2

Ответ:

3/10

Объяснение:

Р(А)=m\n

m-благоприятное событие(сколько всего белых роз)

n-все события которые могут произойти(то есть сколько всего высадили роз)

Р(А)= 9/30=3/10

Answer 3

Probability of the first flower being white

To calculate the probability of the first flower being white, we need to know the total number of flowers planted and the number of white flowers planted.

According to the information provided, a total of 9 white, 15 red, and 6 yellow roses were planted. The first flower to be placed is not specified, so we can assume that any of the 30 flowers could be the first one.

To calculate the probability, we divide the number of white roses by the total number of roses:

Probability of the first flower being white = Number of white roses / Total number of roses

In this case, the probability of the first flower being white is:

Probability of the first flower being white = 9 white roses / 30 total roses

Simplifying the fraction, we get:

Probability of the first flower being white = 3/10

Therefore, the probability of the first flower being white is 3/10.

Please note that the information provided does not specify any additional factors that could affect the probability, such as the order in which the flowers were planted or any preferences for certain colors.
