Using the principle of combination, the number of ways of getting 4 tails from 6 tosses of a coin is 15

Using the principle of combination :

nCr = [n! ÷ (n-r)!r!]

Here, n = 6 ; r = 4

6C4 = [6! ÷ (6-4)!4!]

6C4 = [6! ÷ 2!4!]

6C4 = (6 × 5) ÷ (2 × 1)

6C4 = 30 ÷ 2

6C4 = 15

Therefore, there are 15 ways of obtaining 4 tails from 6 coin tosses
