Can someone please explain step by step. You only need to solve 19 A and 19 B and then I will do the rest (once I learn how to solve it)

step-by-step explanation:

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195

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 %
