3. Two coins are tossed simultaneously 300 times and the outcomes are noted as: Two tails: One tail: No tail: Find the probability of occurrence of each of these events.

As per the question it is given,

Two coins are tossed simultaneously times,

Now,

Total number of times 2 tails come up

P( tails will come up) = Number of times tails come up/Total number of times

the coins were tossed

Total number of times tail come up

P(1 tails will come up) = Number of times tails come up/Total number of times

the coins were tossed

Total number of times no tail come up

P( tails will come up) = Number of times no tails come up/Total number of times

the coins were tossed
