A machine contains two gears. The large gear has 12 teeth and the small gear has 8 teeth. The gears are marked with arrows to show their starting positions. Josh wants to know how many times each gear needs to tum for the arrows to line up again. 10 How many teeth will have touched when the arrows line up again? Large gear tev th: 24 Small gear teeth: 24 P How many full tums does each gear have to make for the arrows to line up again? Large gear tums: Small gear tums:​

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 %
