Answer 1

Answer: The answer is 4\5 i put in 3\40, and 1\8, 4\5 is correct...........

Answer 2

80 tickets in total.
-scott has 10
-tom has 6

you've gotta make those into fractions (a fraction is part of a whole number)
let's do scott first,
the total amount of tickets is 80, right?
Scott bought 10 out of the 80
the fraction will look like this 10/80 (to the lowest terms it's 1/8)
put that into your calculator as (1/8) x 100 and it will give you the probability %

you do the same for tom:
he bought 6 out of 80 tickets
the fraction will be 6/80 (lowest terms = 3/40)
put that into your calculator as (3/4)x 100 and you got your probability %
