A jar contains 24 marbles of which some are green and others are blue. If a marble is drawn randomly from the jar, the probability that it is green is 23. Find the probability of drawing a blue marble from the jar.
13
Given,
Total number of marbles =24
P(green marbles)=23
We know that,
P(green marbles) + P(blue marbles) =1
Because the sum of probabilities of an event and its complementary event is always 1.
⇒ P(blue marbles) = 1 - P(green marbles) =1−23=13
Therefore, P( blue marbles) =13
