If p + q + r = 2,where p, q and r like constants then solve the given relation : rootx-1 -q-r / p + rootx-1 -r-p /q + rootx-1 -p-q / r = 3

the answer would be c:   ax + b = ax + c

step-by-step explanation:

75%

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 %
