Question

use the binomial expansion of (p+q)^n to calculate n=6, p=0.5 binomial distribution

Answer 1

okay

Answer 2

p+q=1
p=0.5
q=0.5

so we just got 1^n = 1^6=1

Answer 3

no need to really expand in this case lol

Answer 4

dam! thank you sooooooooooooooooooooo much!

Answer 5

you're welcome :)

Answer 6

if this p+q is not equal to 1 though, you should refer to the pascal triangle to expand fast
