The figure below shows the dimensions of Aman’s bedroom. Aman wants to put new carpet in the room. Which of the following will help him figure out how much carpet he needs? (All angles in the diagram are right angles.)

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 %

27 +27 or 27times 2=54

the diffrence is 0
