a very large bag contains more coins than you are willing to count. instead, you draw a random sample of coins from the bag and record the following numbers of each type of coin in the sample before returning the sampled coins to the bag. if you randomly draw a single coin out of the bag, what is the probability that you will obtain a quarter? enter a fraction or round your answer to 4 decimal places, if necessary.

The probability of drawing a quarter is 23/100.

The probability of drawing a quarter is the number of quarters in the bag

divided by the total number of coins in the bag.

There are 23 quarters in the bag and 23+20+21+36=100 coins in the bag,

so the probability of drawing a quarter is 23/100.

This is equal to 0.230.
