7 Tony hésite entre deux livrets d'épargne à intérêts simples: • le livret 1, qui propose un taux fixe de 0,5%; • le livret 2, qui propose un taux bonifié à 3% pendant les deux premiers mois, puis un taux de 0,3% ensuite. Tony souhaite déposer un capital de 25 000 € pendentif 1 an. Quel livret va-t-il choisir? 1. Comment faire pour comparer ces deux livrets? 2. Calculer les intérêts I, et la valeur acquise A, pour le livret 1.​

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
