Problema Solution
a bag contains 2 white marbles, 4 blue marbles, and 6 red marbles. if a marble is drawn from the bag what is the probability that it is not white
Answer provided by our tutors
P(marble is not white) = 1 - P(marble is white)
P(marble is not white) = 1 - 2/(2 + 4 + 6)
P(marble is not white) = 1 - 2/12
P(marble is not white) = 1 - 1/6
P(marble is not white) = 5/6
P(marble is not white) = 0.83
