A jar contains 20 yellow marbles, 55 green marbles, and 25 purple marbles. You pick one marble from the jar at random. What is the theoretical probability of picking a green marble
Accepted Solution
A:
So, if the jar has 20 yellow marbles, 55 green marbles, and 25 purple marbles in total it has 100 marbles. (check:20+55+25=100m). Sense there are 55 green marbles out of 100, your theoretical probability will be 550/100(fraction:55 over 100). Simplified its 11/20.Β
