Question

The bias of a coin is 0.6 in favor of heads. what is the probability of flipping 8 or more heads in 10 flips?

Answer 1

I hope you have a graphing calculator!

Basically, you have to do
2nd vars B to get to binomcdf
1-binomcdf(10,0.6,8)
because binomcdf(trials, probability, # of success or less)
Thus we get 0.04636 or 4.636%
