Q4. Check the shape of Binomial distribution for the following cases:

a. n=10, p=0.2

b. n=10, p=0.5

c. n=10, p=0.8

d. n=50, p=0.2

e. n=50, p=0.5

f. n=50, p=0.8

Note: As the number of trials in a binomial experiment increase, the probability distribution becomes bell-shaped. As a rule of thumb, if np10 and n(1-p)10, the distribution will be approximately bell-shaped.
