I have been working on this problem for hours and still can't get it. Can anyone help? It's not multiple choice so I'd need help working it out.

Use the binomial expression (p + q)^n to calculate a binomial distribution with n = 5 and p = 0.3.

This answer is not correct because you it is (p +q) ^n not (p+q) * 5

Alright. Give me a couple of minutes to try to work this out. brb

no problem, thank you :)

bartyrocks3 · Answer

(p + q)^5 = p^5 + (5p^4)(q) + (10p^3)(q^2) + (10 p^2)(q^3) + 5p(q^4) + q^5 

If p = 0.3, then q = 1 - p = 1 - 0.3 = 0.7. 

I`ll let you finish the problem.
