Given:
⇒ Probability of happening of an event = 45%
To Find:
⇒ Probability of event
Now, probability of happening of an event is 45% means non happening event is 100 - 45 = 55%.
⇒ Probability of happening event = 45/100
⇒ Probability of happening event = 0.45
⇒ Probability of non happening event = 55/100
⇒ Probability of non happening event = 0.55
Hence, the correct option is (c) 0.45.
Extra Info:
Probability is the likelihood /chances of a given event's occurence which is expressed as a number between 1 and 0.
