Step 1

*Conditional rule:*

The formula for probability of *A *given *B *is,

Step 2

In a coin tossing, the probability of getting a head and a tail is equal and the corresponding probability of each is equal to ½. Here, the coin is tossed 6 times. Thus, it follows a binomial distribution with n=6 and p=1/2. That is,

Step 3

**Finding the probability that tails occurs exactly 6 times if it is known that tails occurs at least four times:**

The prob...
