Answer: 0.7748
Step-by-step explanation:
Given : Number of bit bulls at the pound = 18
Number of pit bulls have attacked another dog in the last year =4
The proportion of pit bulls have attacked another dog in the last year:
Number of the pit bulls selected = 6
The probability of that none of the pit bulls in Joe's group attacked another dog last year : 
By using binomial , the probability that at least one of the pit bulls in Joe's group attacked another dog last year is given by :-

Hence, the required probability = 0.7748
The radius of a circle should be placed in the Z section making the answer A.
Answer:
Step-by-step explanation:
Depends on the tree.
If it's like a pine or spruce, then I would use maybe 2 inches lattitude. If it's really leafy with big leaves, perhaps a little more lattitude is needed, like maybe 1/2 a foot.
It also depends on the season. Unless the pine or spruce is covered with snow, I wouldn't change the latitude. If it is covered with snow, knock the snow off.
For something like a maple in winter, I'd reduce the latitude to 3 inches......
C, but get someone else opinion too
