There are 15 marbles in total, with 9 of them being white. So the probability of selecting a white marble is:
P(white) = 9/15
Simplifying this fraction, we can reduce it by dividing both the numerator and denominator by 3:
P(white) = 3/5
Therefore, the probability of selecting a white marble from the jar is 3/5 or 0.6 (when expressed as a decimal).
A Jar has 9 white marbles and 6 black marbles. What is the probability of selecting a white marble?
