Step-by-step explanation:
{0,1,2,3,4,5,6,7,8,9}--set of numbers from 0 to 9
{2,3,5,7}---set of prime numbers from 0 tp 9
there are 10 numbers in the first set and 4 numbers in the second set.
4/9 is the probability that the digit he selects is a prime number
Hope that helps :)
Answer:
7 1/5
You said that she poured 1 1/5 pouches in each cup. There are 5 cups, so multiply 1 1/5 by 5.
(e.g)
1 1/5+1 1/5= 3 because 1+1=2 & 1/2+1/2=1 so you add them and get 3
Do that twice and you get 6
then you have 1 one more cup left so add 1+6=7 then add the half 7+1 1/2=7 1/2
Your Welcome
