SPADES ACE AND HEARTS KING
let Y = the number of aces and/or kings that show up in the 5 community cards( or "board") to match the teacher's cards. The probability distribution of y is as follows.
y p(y) a) find mean of y
0 0.5126 b) standard deviation y
1 0.3844 c) would it be unusual if the 'board' contained 3 cards that matched the teacher's holdings?
2 0.0938 use the z-score to explain
3 0.0089 d)what is the expected range for the number of cards on the flop that will
4 0.0003 match the teacher's cards/
