Huge help needed ! im lost and need an explanation to the correct answer. (will mark brainliest)

angle addition postulate

2x=56

step-by-step explanation:

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 %

what is the your question?

tried on you are knowing that we can't leave the picture in the graph ok no problem now you need to send it in the question group
