Solution:
We are given
n = 4
p = 0.8
q = 1 - p = 1 - 0.8 = 0.2
We have to find P(X≤2)
P(X≤2) = P(X=0) + P(X=1) + P(X=2)
P(X=x) = nCx*p^x*q^(n - x)
P(X=0) = 4C0*0.8^0*0.2^4 = 1*1*0.2^4 = 0.0016
P(X=1) = 4C1*0.8^1*0.2^3 = 4*0.8*0.2^3 = 0.0256
P(X=2) = 4C2*0.8^2*0.2^2 = 6*0.8^2*0.2^2 = 0.1536
P(X≤2) = 0.0016 + 0.0256 + 0.1536
P(X≤2) = 0.1808
Required probability = 0.1808
