In 3 billion repetitions of an experiment, a random event occurred in 500 million cases.

i know the probability of this event is 1/6 – what is the expected probability of the complement of the event?

The expected probability of the complement of the event is:

We know that for any event A and the complement of the event i.e. the sum of the probabilities of both the events is equal to 1.

i.e. if P denote the probability of an event then we have:

Here we have the probability of event A as:

Hence,

           Hence, the answer is:

for b its (t) and c its (d)
