Hannah received $30 for her birthday and bought 3 shirts that were all the same price. if she had $9 left over, which equation shows how to determine how much each shirt cost? a.3x = 39 b.3x = 30 c. x + 9 = 30 d.3x + 9 = 30

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 %
