Если вероятность события K равна:

а) 0,85, то вероятность события K' (не наступления события K) будет равна 1 - 0,85 = 0,15. Тогда вероятность события K будет равна P(K) = 0,85.

б) 1/2, то вероятность события K' будет равна 1 - 1/2 = 1/2. Тогда вероятность события K будет равна P(K) = 1/2.

The probability of event K is 0.85.

The probability of event K is 1/2.

To calculate the probability of event K, we need to know the probability of its complement, event K'. The probability of event K can be calculated using the following formula:

P(K) = 1 - P(K')

If the probability of event K is 0.85, then the probability of event K' is 1 - 0.85 = 0.15.

P(K) = 1 - 0.15 = 0.85

Therefore, the probability of event K is 0.85.

b) If the probability of event K is equal to 1/2, then the probability of event K' is 1 - 1/2 = 1/2.

The following question may be like this

In some random experiment, event K may occur. Find the probability of event K], if the probability of event K is equal to a) 0,85 b)1/2
