The distribution follows binomial distribution where:
In this case:
---- the theoretical probability of rolling 2
So, the mean of 2's is calculated using:

Answer:
Option B, The sum will be positive if the absolute value of the negative number is greater than the absolute value of the positive number.
Ex. (-1 + 10 = +9) 10 is greater than -1 so it will result positive
AND
Option, E The sum will be negative if the absolute value of the negative number is greater than the absolute value of the positive number.
Ex. (-10 + 1 = -9) -10 is greater than 1 so it will result negative
Answer:
D. 8/15
Step-by-step explanation:
4/5 = 2/3 +1/3
We need to multiply by 6 to find answer as 3 is a divider of 6
4 x 6 =24
5 x 6 =30
24/30
Then we find 1/2 of 30 and add this to make 3/3
Just like 1/2 of 2 = 1 and 2+1 = 3
30 / 2 = 15
15 + 30 =45
The answer is 24/45
We then reduce this fraction by 3 as 6 + 8 do not divide into 45
24/45 = 8/15
The answer is 8/15
