  • Probability and Hole Card selection

    If AA is considered an unfair coin it merely means that AA wins more than it loses

    example of an unfair coin

    You have 14 coins in a bag . 2 of them are unfair in that they have a 30% chance of coming up heads when flipped ( the rest are fair coins ). You randomly choose one coin from the bag and flip it 4 times.

    What is the probability , written as a percentage , of getting 4 heads ? Round your answer to the nearest hundredth of a percent.

    omg !!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    14 coins total
    2 fair 12 unfair
    2 fair are 30%
    12 unfair are 50%
    4 flips

    2/14 X .30 X .30 X .30 X .30 = 0.0011571428571429 +

    12/14 X.50 X.50 X.50 X.50 = 0.0535714285714286 = 0.054728 = 5.47 %

    5.47% odds are against you here

    tadah !!!!!
