2expressions where the solution is 19

5 + 14 and 12 + 7

Step-by-step explanation:

1.10+9=19

2.11+8=19

3.2(9)+1=19 (2(9)=18+1=19)

4. 3(6)=1=19 (3(6)=18+1=19)

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 %
