A. Simon needs 125 ml of milk to make 4 pancake.  B. He needs 7 and a half grams of butter to make 12 pancakes

Step-by-step explanation:

A) If we know that 250 ml milk can help make 8 pancakes then we could set up a proportion as to how many milk we need to make 4 pancakes.

    Solve by cross  product,

8x = 1000

x = 125  

B) The same with this we could also set up a proportion. We know you need 5 grams of butter when making 8 pancakes.

   solve by cross product

60 = 8x

x = 7.5

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

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 %
