What exactly is the rule of this? (in words) 7.5 x 1000 = 7500
5.9 x 10 = 59
9.4 x 100 = 940

8.3 / 1000 = 0.0083
6.5 / 10 = 0.65
6.6 / 100 = 0.066

/ means divided by
x means multiply

the rule is scientific notation. if you are multiplying, move the decimal point over the amount of zeros to the right. if dividing, move the decimal point over to the left for the number of zeros there are.

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 %
