**Damon**, Friday, June 4, 2010 at 8:52pmp tails in 1 toss = .5

binomial distribution

p = .5

number of trials , n , = 6

number of successes = 2,3,4,5,6

number of failures = 0,1

so easier to work it backwards

what is the probability of 0 or 1 heads

p is still .5

p(0 heads) = C(6,0) (.5^0)(.5)^6 = .0156

p(1 heads) = C(6,1)(.5^1)(.5)^5 = 3*.03125 = .09375

sum = about .11

1 - .11 = .89
