Answer:
Step-by-step explanation:
Given that Helene is finding the sum (9 + 10i) + (–8 + 11i).
Also given that She rewrites the sum as (–8 + 11)i + (9 + 10)i.
The mistake she did is in the second term distributing i.
(9+10i) is not equal to (9+10)i
Similarly (-8+11i) is not equal to (-8+11)i
The correct method she should have done is
grouping real terms together and imaginary terms together and finding the sum
She made a mistake of taking out i from real term without changing the real term appropriately.
Thus she did the mistake of grouping unlike terms and factorising.

Answer:
The probability of you winning is 1/3
No, it is not a fair game
Step-by-step explanation:
The first thing we need to have here is the sample space. This refers to the set of all possible results that can occur from the rolling.
Please check attachment for this
Kindly note that the total number of possible outcomes is 36.
And in the attachment, sums which are divisible by 3 are circled.
The number of circles we can count is 12
Thus, the probability of you winning would be number of circles/total number of outcomes = 12/36 = 1/3
Is it a fair game?
No, it is not
It can only be a fair game if the probability of winning equals probability of losing ( which is 18/36 = 1/2 or 0.5)
