How many 35 cup servings are in 13 of a cup of rice? (in simplest fraction form)

A)1/2
B)5/3
C)5/9
D)9/15

i believe the answer is c.

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 %

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 %
