La confiture
Léo a ramassé des fraises pour faire de la confiture.
1) Il utilise les proportions de sa grand-mère : 700 g de sucre pour 1 kg de fraises.
Il a ramassé 1.8 kg de fraises. De quelle quantité de sucre a-t-il besoin ?
2) Après cuisson, Léo a obtenu 2,7 litres de confiture.
Il verse la confiture dans des pots cylindriques de 6 cm de diamètre
et de 12 cm de haut, qu'il remplit jusqu'à 1 cm du bord supérieur.
Combien pourra-t-il remplir de pots ?
3) Il colle ensuite sur ses pots une étiquette rectangulaire qui fait tout le
tour du pot.
Quelle est la longueur de cette étiquette ? (Arrondir au 10ème)
Fraises

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )
