The answer is 50%
if you list out the possibilities, you get
(H being heads, T being tails)
HHH <- 3 heads
HHT <- 2 heads
HTH <- 2 heads
HTT
THH <- 2 heads
THT
TTH
TTT
we counted 4 of them to have at least 2 heads out of the 8 possibilities
4/8 = 1/2 which is 50%
So you would subtract 0.32 from 1.16 because it is the initial amount. Then divide what you get from that (0.84) by .21. You're gonna get .04- but that's not the answer because you have to add the initial ounce that is worth $0.32. So The answer is B
The answer is C ... or you could say n<3
It is C: Given, Reflexive Property
