A bag contains 15 red 27 white and 8 green marble. A boy takes one marble out of the bag at random find the probability that marble is white is white.

There are a total of 15 + 27 + 8 = 50 marbles in the bag. The probability of pulling a white marble out of the bag is:

P(white) = number of white marbles / total number of marbles
P(white) = 27 / 50

Therefore, the probability that the marble chosen at random is white is 27/50 or approximately 0.54 or 54%.
