Remember you can do anything to an equation as long as you do it to both sides
a=age
500 reduced by 2 times a is equal to 388
500-2a=388
minus 500 both sides
-2a=-112
divide both sides by -2

you are 56

Answer: The answer is 0.38
Step-by-step explanation:
Well, everything is given, as stated in the question "the probability that a student is a girl and in an art class is 0.20."
It's given that the probability that a student is a girl is 0.52.
However, in the question, it said that it's given a student is a girl.
You have the probability that a student is a girl and in art class, so you need to find what 0.52 was multiplied by which would be the probability of someone being in art class. Knowing this you can do 0.20 / 0.52 to get 0.38.
