Answer:
(a) 30 & younger (no facial hair are 1,2,4,9. with facial hair are 10,12,14)
older than 30 (no facial hair are 3,4,8 . with facial hair are 6,7,11,13,15)
The volume of figure B is 15
Answer:
Step-by-step explanation:
Area of box = 14^2 = 196 in^2
Radius r of pizza = 12/2 = 6
Area of pizza = πr² = 36π ≈ 113.04 in^2
Answer:
P(x) = 8Cx * p^x * (1 - p)^(8 - r) ; r = 0, 1, 2
Step-by-step explanation:
Given that:
Total Number of cameras (n) = 8
Defective cameras = 4
X: number of defective cameras
For a binomial distribution :
P(x) = nCx * p^x * (1 - p)^(n - x)
Probability of success (p) on each trial is the same = (total number of samples / number of defective samples) = 8/4 = 0.5
If 2 samples are chosen at random :
Then, the binomial probability distribution will be :
P(x) = 8Cx * p^x * (1 - p)^(8 - r) ; r = 0, 1, 2
