Whole numbers are like 0,1,2,3,4,5...
the smallest one is 10
prime numbers

if you do think it's a prime number, go to BBBBBBB
AAAAAAA
2,3,5,7
2+3+5+7=17
a+b=10+17=27
BBBBBBBBBBB
1,2,3,5,7
1+2+3+5+7=18
a+b=10+18=28
if you do not think a is a prime number, then the answer is 27
if you do think 1 is prime number then the answer is 28
The probability that all marbles are yellow is
(7/20) (7/20) (7/20) = 343/8000
We are given
x = 2 and 3
u = 2.5
s = 0.5
Getting the z score
z = (2 - 2.5) / 0.5 and (3 - 2.5)/ 0.5
z = -1 and 1
The percentage is
1 - 0.1557 = 81.5%
