p= 0.30
Step-by-step explanation:
Binomial distribution :
Let x be a binomial variable.
The probability of getting success in x trials is given by :-
, where n is the total number of trials and p is the probability of getting success in each trail.
Given : The proportion of parolees from prison return to prison within 3 years= 0.30
We assume that whether or not one prisoner returns to prison is independent of whether any of the others return to prison.
⇒ p =0.30
Let the random variable X be the number of parolees out of 15 that return to prison within 3 years.
⇒ n= 15
Step-by-step explanation:
One way
x3 + 11x2 - 3x - 33
x2(x + 11) - 3(x + 11)
(x + 11) (x2 - 3) are the factors
As2uming the drum is a circle, the best estimate would be 9π
because 9 is the diameter and you need to multiply it by π

64 = 36 + x square
minus 64 with 36
64 - 36 = 28
cancel the square with square root
x square = 28
square root of 28 is 5.3
5.3 x 5.3 = 28.09
