At a middle school 30% of the students walk 12.5% are dropped off by car and the remaining take the bus
If there are 800 students who attend this school how many students use each form of transportation

240 walk, 100 are dropped off and 460 take the bus.

Step-by-step explanation:

first, find the bus percentage by subtracting 30 and 12.5 from 100 (which is 57.5%)

now put these percentages in decimal form: 30 -> .30 and 12.5 -> .125 and 57.5 -> .575 and multiply them (separately to 800)

.30 x 800 = 240

.125 x 800 =100

.575 x 800 = 460

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 %
