Question 996839: a coin is biased each flip you have 55% chance of getting a head . if you flip this biased coin 8. times . what is the probability you will get the same number of heads and tails Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! That is the probability of 4 heads in 8 tries
It is 8C4(0.55)^4(0.45)^4=0.2627
The 8C4 is the number of ways 4 heads can occur.
