Answer:
ahh pythagoras' theorem, my old nemesis...
Step-by-step explanation:
ratio of 9:2
means for every 9 cows there are 2 horses
72/9 = 8
8 x 2 = 16
there are 16 horses
<span>5,391 divided 77 = 70.01...........
by estimation
70</span>
We will consider the following possibilities:
Wins none, wins first only, wins second only, wins both
a) Wins none:
Chances are: 75% x 65% = 48.75%
Thus, there is a 48.75% chance that the horse will sell at $15,000
b) Wins first only:
Chances are: 25% x 65% = 16.25%
c) Wins second only:
Chances are: 75% x 35% = 26.25%
Thus, the chances of the horse selling at $60,000 are 16.25 + 26.25
= 42.5%
d) Wins both:
Chances are: 25% x 35% = 8.75%
The chances that the horse will sell at $100,000 are 8.75%
