Question

Вероятность того, что новый принтер прослужит больше года, равна 0,98. Вероятность того, что он прослужит больше двух лет, равна 0,84. Найдите вероятность того, что он прослужит меньше двух лет, но больше года.

Answer 1

$P=0,98-0,84=0,14$

Ответ: $0,14$

Answer 2

Calculation of Probability

To find the probability that the printer will last less than two years but more than one year, we can subtract the probability of it lasting more than two years from the probability of it lasting more than one year.

Given: - Probability of the printer lasting more than one year = 0.98 - Probability of the printer lasting more than two years = 0.84

To find the probability that the printer will last less than two years but more than one year, we can subtract the probability of it lasting more than two years from the probability of it lasting more than one year:

Probability = P(>1 year) - P(>2 years)

Probability = 0.98 - 0.84

Probability = 0.14

Therefore, the probability that the printer will last less than two years but more than one year is 0.14.
