Then by applying the formula for sum to infinity of a geometric progression,
Answer:
The answer is A
Step-by-step explanation:
If you plug in the numbers it looks like this:
(A) 5(2) + 10(5) = 60
(B) 10(2) + 5(5) = 45
(C) 7(2) + 8(5) = 54
(D) 8(2) + 7(5)
so a is the only one that equals 60
Step-by-step explanation:

Answer:
probability that Shaun loses both games
Step-by-step explanation:
Games are independent, so we find each separate probability, and multiply them.
In a chess club the probability that Shaun will beat Mike is 3/8.
So
probability that Shaun loses.
The probability that Shaun will beat Tim is 5/7 .
So
probability that Shaun loses.
What is the probability that Shaun loses both games?
This is:
