case 1: all 6 are red. P(red) = 34/94
case 2: 5 reds and 1 blue were drawn. P(red) = 35/94
...
case 7: all 6 are blue: P(red) = 40/94
so, what do you think?
an urn contains 40 red chips and sixty white chips. six chips are drawn out and discarded, and a seventh is drawn. what is the probability that the seventh chip is red?
