Took the test and I got it right :)

The theoretical probability of picking a one-dollar coin from the piggy bank before the draw is 50%, But the experimental probability, based on the draw, is 60%

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

P(E) = Number of favorable outcomes / total number of outcomes

Jonathan's piggy bank contains 20 nickels, 30 quarters, and 50 one-dollar coins.

He picks 20 coins from the bank at random; 12 of these coins are one-dollar coins.

The total number of one-dollar coins = 50

Total number of coins the piggy bank contains = 100

The theoretical probability of picking a one-dollar coin from the piggy bank before the draw = 50/100

                           = 1/2

But the experimental probability, based on the draw, is 60%.
