What is the probability that neither prisoner goes back to prison when the state’s recidivism is 25% and 25% of released prisoners end up back in prison (within three years).

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

246

step-by-step explanation:

b) yes

step-by-step explanation:

let the statements be named as,

statement 1: if the power has been cut, then the refrigerator does not work.

statement 2: the refrigerator does not work.

conclusion: the power has been cut

now, 'law of detachment states that if we have the statements given as,

1. if p, then q.

2. p

then, we get the true statement or conclusion as q'.

thus, on comparing, we get that,

p: if the power has been cut.

q: the refrigerator does not work.

so, the argument is true by the law of detachment.
