First you need to know the prime numbers from 1-10.
They are 2, 3, 5, 7,
1st draw: P(prime) = 4/10
2nd draw: P(prime) = 3/9
Multiply these numbers 12/90 = 2/15
80% bc 20/25 equals 4/5 and 4/5 equals x/100 and when you do that math it equals 80%
The width is 2 and the length is 4 hope this helps!
I think this is it not sure tho
