To increase sales, an online clothing store began giving a 50% off coupon to random customers Six customers each made purchases from the website the binomial random variable and  mean and standard deviation of X  is mathematically given as

X ~ Bin(n = 6, p = 0.2)

x= 0.9798

<h3>What is a binomial random variable?</h3>

Generally, the equation for is mathematically given as

P(coupon) = 1/5

P(coupon)= 0.2

the binomial distribution

X ~ Bin(n = 6, p = 0.2)

Therefore, The mean and standard deviation of X

пВ = np \\np= 6* 0.2 = 1.2\\

x=\sqrt{ np(1 - p)} \\ x=\sqrt{ 6 * 0.2 + (1 -0.2)} \\

x= 0.9798

In conclusion, mean and standard deviation of X

x= 0.9798
