how should i calculate the expected frequency of a fitted binomial distribution

Question

An experiment is repeated 100 times and a fitted binomial distribution is obtained as follows:

Calculate the Expected frequencies for the fitted binomial distribution.

Answer 1

₅C_x means 5!/(x!(5-x)!) The coefficients for x = 0..5 are 1,5,10,10,5,1

Otherwise find the 6 frequencies by plugging into the equation for x except the term should be (.6)^5-x

not (.6)^n-x) and multiplying each probability by 100 (n)

The frequency for X=3 is 100(10)(.4)³(.6)² = 23.04

I'll leave the others for you.
