In the game of "odd man out" each player tosses a fair coin. if all the coins turn up the same except for one, the player tossing the different coin is declared the odd man out and is eliminated from the contest. suppose that three people are playing. what is the probability that someone will be eliminated on the first toss?

The options are H,H,T or T,T,H

HHT: 1/2 x 1/2 x 1/2  = 1/8

TTH: 1/2 x 1/2 x 1/2  = 1/8

HHT or TTH: 1/8 + 1/8 = 2/8 = 1/4

1 out of 4 = 1/4 = 25%

coin flip

sorry if this isnt what you're looking for i dont really understand the question

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
