What percent of the students who spend 4-8 hours a week on screens reported a
grade average below 80? Round your answer to the nearest whole number percent.

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
