For each of the three-digit numbers with no digits zero, the difference between the number itself and the product of its digits is calculated.
The largest such difference is
(A) 110
(B) 270
(C) 902
(D) 910 (E) 927

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 %
