Suppose the probability of an event occurring is p(a), and the probability of the event not occurring is p(a’). if p(a)= x and p(a’)= y, which of the following equations must be true

The correct answer is A) t = 1-s.

The probability of the complement of an event is the probability of the event subtracted from 1; in other words

P(A') = 1 - P(A)

Since P(A') = t and P(A) = s,  

t = 1-s

- 70

this is the answer for you hope it

6 hours 48 min

step-by-step explanation:

68÷5=13.6

13.6×30=408min=6 hours 48 min.
