Question

Find the probability.
There are three nickels, four dimes, and five quarters in your pocket. You randomly pick
a coin. It is a nickel or a dime.

Answer 1

Answer:

0.583

Step-by-step explanation:

You have a total of 12 coins in your pockets (3 nickels + 4 dimes + 5 quarters).

There are 7 nickels/dimes (3 + 4), meaning you have a 7/12 chance of picking either a nickel or a dime.

7/12 simplifies to 0.583.

You have a 0.583% chance of picking either a nickel or a dime.
