A teacher has found that the probability that a student studies for a testis 0.68, and the probability that a student gets a good grade on a test is 0.67, and the probability that both occur is 0.48 A. Given that a student studies, find the probability that the student gets a good grades

the answer is c.

step-by-step explanation:

or

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
