Question 376701: if there are 8 red disks numbered 1 through 8, and 4 yellow disks numbered 9 through 12 find probability of selecting a disk numbered 3, given that a red disk is selected Answer by jim_thompson5910(35256) (Show Source):
You can put this solution on YOUR website! Since it is "given that a red disk is selected", this means that we know that the selected disk is numbered 1 through 8.
Since 3 is in that interval (of 8 numbers) and it is the only number that we want, this means that the probability of selecting 3 given that a red disk was selected is
