Liliana has a bag of marbles. the bag contains 18 black, 15 red, 11 blue, and 8 white marbles. liliana randomly takes a red marble from the bag and leaves the marble on a table. what is the probability that she will next take a red or a white marble from the bag?

Respuesta :

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

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
