in texas, 30% of parolees from prison return to prison within 3 years. suppose 15 prisoners are released from a texas prison on parole. assume that whether or not one prisoner returns to prison is independent of whether any of the others return to prison. let the random variable x be the number of parolees out of 15 that return to prison within 3 years. what are the values of the parameters for the binomial random variable x?

n =

p =

 n= 15

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

you divide the cost ($15) by the quantity (6) to get your questions answer. the yo-yo costs $2.50. hope this : )!

step-by-step explanation:

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
