Answer:
Step-by-step explanation:
Sorry but I can’t see the picture
The probability of any event is between 0 and 1. 0 means impossible and 1 means certain.
It could also be written with the percents: 0% and 100%.
Whole numbers are like 0,1,2,3,4,5...
the smallest one is 10
prime numbers
I do not accept 1 as a prime number, if you agree, go to AAAAAAAAA
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
20 because of the whole is 40 and the shaded part is by 20 you just take half of 40 and you get 20
