Determine the gear ratio for a bike with 45 front teeth and 18 rear sprocket teeth.

18/45 = 0.4

45/18 = 2.5

18(45) = 810

45 – 18 = 27

just did it, it's 45/18 = 2.5

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 %

answer: b
