Question 104130: I need help filling in the numbers in an equation that is used for finding binomial probabilty:
P(k successes)= 
This is for a project that I am doing and it includes tossing one coin 100 times and then separating the 100 results into groups of 5 (20 groups/trials total). My teacher said that the numbers for the equation are as follows: n=5 because each trial has 5 tosses, k=6 because heads can show up 6 different ways in a trial ( not at all, once, 2 times, 3 times, 4 times, and 5 times), and
p(not P)=.5 because it's a fifty/fifty chance of one toss being heads or tails. I filled these into the equation and it always equals 0. Can you help me find the right numbers to fill in this equation and where they should go into it? By the way, the k after (p) should be an exponent [not the (1-p)], and the n-k should be an exponent.

You can put this solution on YOUR website! 5C6 p^6 q^(n-6)
--------------
5C6 is meaningless as it is the number of groups of size 6
when you have 5 object to choose from.
