Can you help? thank youu

13 in.

Step-by-step explanation:

perimeter of triangle = 3 1/3+5 1/2 + 4 1/6

=10/3+11/2+25/6

=20/6+33/6+25/6

=(20+33+25)/6

=78/6

=13 inch.

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 %
