Answer:

The number of ways in which no. of tails is equal to the no. of heads = 20 ways

Step-by-step explanation:

Number of identical coins = 6

For equal number of heads and tails, among 6 coins three heads will have to accompany three tails.  

\text{Out of 6 coins, 3 heads can be obtained in }_{3}^{6}\textrm{C}\text{ ways}\\\\\bf\implies \textbf{Required number of ways = }\frac{6!}{3!\times 3!}=20

Hence, The number of ways in which no. of tails is equal to the no. of heads = 20 ways
