What is probability?

Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.

A bag contains 12 marbles of which 4 are red and 8 are blue.

If two marbles are drawn at random.

Then the probability that both are blue will be

The favorable events will be

Favorable events = ⁸C₂

Favorable events = 28

The total events will be

Total events = ¹²C₂

Total events = 66

Then the probability will be

P = 28/66

P = 0.4242

P = 42.42%
