# If x is a binomial random variable with n = 10 and p = 0.8, the mean value of x is?

**Solution:**

Given, x is a Binomial Random Variable with parameters, p = 0.8 and n = 10.

x ≈ B(10, 0.8)

We have to find the mean value of x.

Mean = np

Mean = 10(0.8)

Mean = 8

Therefore, the mean value of x is 8.

**Example: **

If x is a binomial random variable with n = 10 and p = 0.3, the mean value of x is?

**Solution:**

Given, x is a Binomial Random Variable with parameters, p = 0.3 and n = 10.

x ≈ B(10, 0.3)

We have to find the mean value of x.

Mean = np

Mean = 10(0.3)

Mean = 3

Therefore, the mean value of x is 3.

## If x is a binomial random variable with n = 10 and p = 0.8, the mean value of x is?

**Summary:**

If x is a binomial random variable with n = 10 and p = 0.8, the mean value of x is 8.
