You mow 1/3 of the lawn. Your sister mows 2/5 of the lawn. What fraction of the lawn is left to mow?​

4/15

Step-by-step explanation:

1/3+2/5 change it to 5/15+6/15=11/15 4/15 left of the lawn

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 %
