Answer:
-- (a)
-- (b)
-- (c)
Step-by-step explanation:
Given
Represent the probability that a 40-year-old male lives to 41 be P(A).
So:
Solving (a): Two selected live to be 41
This event is represented as: AA and the probability is:
Solving (b): Five selected live to be 41
This event is represented as: AAAAA and the probability is:
Solving (c): At least one of five selected will not live to be 41.
In (b), we calculate the probability that all 5 lives to be 41.
When this is subtracted from 1, it gives the probability that at least one of them will not is:.
So, we have:
(c ii).
It will be unusual because the probability that at least one of the selected 5 will not live to 41 is very low.
Answer:
9x+14y
Step-by-step explanation:
First Multiply the number outside of the brackets with the numbers inside the brackets. Ex:3 x 3x and 3 x -y
17y-2x+3(3x-y)+2x
That should get you to this.
17y-2x+9x-3y+2x
Next combine like terms.
14y+9x
Hope this helps!
