Ajar contains 3 pennies, 5 nickels, 4 dimes, and 6 quarters. if a coin is selected at random, what is the probability of selecting a penny?

1/6

Step-by-step explanation:

We know this because we have to first add up all of the coins, bringing us to 18. Then, to make the fraction of the probability of selecting a penny at random, we'd simply do 3/18. This simplified would be 1/6

1/6 chance of selecting a penny

Step-by-step explanation:

To find the probability of something, we first find the number of times the thing occurs over the total number of things. Since there are 3 pennies, that is our numerator. Since there are a total of 3+5+4+6 = 18 coins, 18 is our denominator. So 3/18 is our answer which can be simplified to 1/6.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
