Question

В среднем 9 керамических горшков из 75 после обжига имеют дефекты. Найдите вероятность того, что случайно выбранный после обжига горшок не имеет дефекта.​

Answer 1

Ответ: 0.88

Объяснение:

из 75 без дефекта 75-9=66, значит, искомая вероятность равна 66/75=0.88

Answer 2

Probability of a randomly selected ceramic pot not having defects after firing

To find the probability that a randomly selected ceramic pot does not have defects after firing, we need to determine the proportion of pots without defects out of the total number of pots.

According to the information provided, there are 75 ceramic pots after firing, and on average, 9 of them have defects. Therefore, the number of pots without defects would be 75 - 9 = 66.

To calculate the probability, we divide the number of pots without defects by the total number of pots:

Probability = Number of pots without defects / Total number of pots

Probability = 66 / 75

Calculating this, we find that the probability of a randomly selected ceramic pot not having defects after firing is approximately 0.88, or 88%.

Please note that the information provided does not specify the distribution of defects among the pots, so we assume a uniform distribution for this calculation.
