There are 12 state quarters and 5 regular quarters in a bag. rees randomly picks up a quarter and then puts it back in the jar and randomly picks another without looking. if the first quarter was a state quarter, what is the probability that the second quarter will be a regular quarter? write as a simplified fraction.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

if you need just tell me and i will come to the rescue.
