Given: \overline{AB} \cong \overline{AC} AB
≅
AC
and \angle BAD \cong \angle CAD.∠BAD≅∠CAD.

Prove: \angle DBC \cong \angle DCB∠DBC≅∠DCB.

Note: quadrilateral properties are not permitted in this proof.

i’m here for points.

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 %
