Y = k / x
2 = k / 4
k = 8
Therefore, the answer for this question would be (4,2)
Answer: 7 pigeons sitting on the branches, 5 pigeons under the tree
=12 in total
Step-by-step explanation:
Upper branch has x pigeons, lower has y.
Top branch said: "If one of you flies up to us our number will be double yours":
Well, if one of the bottom branch flies up, the top branch will have x+1 birds and the bottom will have (y−1). The top will have double the bottom, so:
x+1=2(y−1)
Top branch said: "If one of us flies down to you, our numbers will be equal":
Now, the top branch will have x−1 and the bottom y+1. The numbers should be equal:
x−1=y+1
Answer:P(win|regular) = 0.84
P(win|prevent) = 0.70
Conclusion: You are more likely to win by playing regular defense.
Step-by-step explanation:
Divide the regular defense wins(42) but the total of regular defense (50) and you get 0.84.
Then divide the prevent defense wins(35) by the total of prevent defense(50) and you get 0.70.
Since the regular defense is more than the prevent defense, then you are more likely to win by playing the regular defense. (:
