Question

Let X be the number of heads obtained in 40 independent tosses of a fair coin. Then X is a Binomial random variable with
​

Answer 1

X is a binomial random variable with the number of trials as 40 and the probability of success is 0·5.

Explanation :

• The Binomial random variable can be defined as the random variable X that represents the number of successes in n trials.
• It is determined by the values of the number of trials, n and the probability of success, p.
• Here, the binomial experiment is tossing a coin 40 independent times. Let X be the number of success to get heads in each of 40 trials, then the probability of success will be  $\frac{1}{2}$  

Answer 2

Answer:

Let X be the number of heads obtained in 40 independent tosses of a fair coin. Then X is a Binomial random variable with
