Since you took a red marble from the bag and didn't put it back, you now only have 14 red marbles to pick out of, and the total number of marbles i in your bag is only 51. Probability of choosing red or white is:
(14/51) + (8/51) = 22/51
(14/51) + (8/51) = 22/51
The probability that she will next take a red or a white marble from the bag is 23/42
What is probability?
Probability is the likelihood or chance that an event will occur.
Probability = expected/Total
Total outcome = 18 +15 + 11 + 8
Total outcome = 42
Pr(red marble) = 15/42
Pr(white marble) = 8/42
Pr( red or a white marble) = 15/42 + 8/42
Pr( red or a white marble) = 23/42
Hence the probability that she will next take a red or a white marble from the bag is 23/42
