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.
