You can put this solution on YOUR website!
P(X = x) = (n C x)*(p)^(x)*(1-p)^(n-x)

P(X = 5) = (5 C 5)*(0.51)^(5)*(1-0.51)^(5-5)

P(X = 5) = (5 C 5)*(0.51)^(5)*(0.49)^(5-5)

P(X = 5) = (1)*(0.51)^(5)*(0.49)^0

P(X = 5) = (1)*(0.0345025251)*(1)

P(X = 5) = 0.0345025251

So the probability is 0.0345025251
