Answer:
Helene is right
Step-by-step explanation:
Mathematically, the expected values is defined as the sum of all the possible outcomes that an event can have times the probality of the respective outcome:
x = ∑ p *i,
where x is the expected value, i represents every outcome that can occur, and p is the probability of said outcome.
Now, for the case of a dice, the expected value would be:
x = 1 * 
+ 2 * + 3 * + 4 * + 5* + 6 * ,
as every outcome has the same chance of happenning. Solving we get that:
x= *(1 +2 +3 +4+5+6) = * 21 = 3.5

Answer:
15
Step-by-step explanation:
To get the next number you have to subtract by 9, 51-9=42, 42-9=33, 33-9=24, and so 24-9=15. The pattern is n-9 (n=previous number) and the answer is 15
