Answer:
The expected profit is $10,600.
Step-by-step explanation:
The expected profit can be calculated as the sum of the possible outcomes weighted by their probability of occurrence.
In this case, there are four possible outcomes:
1) The horse win both races. The value of the horse will be $100k-$20k=$80k.
The probability of this outcome is:

2) The horse win the first race, but lose the second one. The value will be $50k-$20k=$30k.
The probability is:

3) The horse lose the first race, but win the second one. The value will be $50k-$20k=$30k.
The probability is:

4) The horse lose both races. The value will be $10k-$20k=-$10k.
The probability is:

Then, the expected profit can be calculated as:

-- Take a piece of paper
-- Take a pencil or a pen
-- Write the first nine or ten terms of the sequence:
Term Value
#1 0
#2 0.5
#3 1
#4 1.5
#5 2
#6 2.5
#7 3
#8 3.5
#9 4
#10 4.5
-- Now, find the graph of that sequence of numbers.
Hint: It's Graph-D .
Answer:
it reduces to 7:8
Step-by-step explanation:
just put it like a fraction like 140/160. it simplifies to 7/8
It is actually b I hope I am correct
