1. The probability of both coins quarters will be 1/15.

   What is probability?

   Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

   If you have 3 quarters, 5 dimes, and 2 nickels in your pocket.

   Then the total number of the events will be

   Total event = 3 + 5 + 2

   Total event = 10

   Then the probability that you will reach into your pocket and choose a coin, keep it in your hand, then reach in to choose another coin, and both coin’s quarters will be

   P = (3/10) x (2/9)

   P = 1/15

   Then the probability of both coins quarters will be 1/15.
