P(Y then X)
Answer to Problem 28P
Explanation of Solution
Given:
You choose a tile at random from a bag containing 2 tiles with X, 6 tiles with Y, and 4 tiles with Z.You pick a second tile without replacing the first.
Formula Used:
Calculation:
Tiles with X = 2
Tiles with Y = 6
Tiles with Z = 4
Total number of tiles = 12
Number of favorable outcomes of Y tiles in first turn = 6
Total number of tiles left after first tile is drawn out of the box = 11
Number of favourable outcomes of X tiles in second turn = 2
