P (X>4) = 0.624

Step-by-step explanation:

n = 10

p = 0.5, q = 1 - p = 0.5

Two fifth of 10 = 2/5 x 10 = 4

It means that we have to find probability P (X>4).

P (X>4) = 1 - P (X=0) - P (X=1) - P (X=2) - P (X=3) - P (X=4)

We know that

P (X>4) = 1 - P (X=0) - P (X=1) - P (X=2) - P (X=3) - P (X=4)

P (X>4) = 1 - 0.0009 - 0.0097 - 0.043 - 0.117-0.205
