Question

If the probability of happening of an event is 5/11,what is the probability of not happening an event?

Answer 1

probability of event not happening= 11/11-5/11=6/11

Answer 2

Given that probability of happening of an event P(E) = (5/11).

We know that P(E) + P(not E) = 1.

= > (5/11) + P(not E) = 1

= > P(not E) = 1 - (5/11)

= > P(not E) = (11 - 5)/11

= > P(not E) = 6/11.

Therefore, the probability of not happening an event = (6/11).

Hope this helps!
