Assuming that each marble can be picked with equal probability, we notice that there is a total of
marbles, of which 2 are red.
So, the probability of picking a red marble is
In fact, as in any other case of (finite) equidistribution, we used the formula
Step-by-step explanation:

Step-by-step explanation:
absolute value, if it's a negative number, will be positive. if it's a positive number, it will stay positive.
Answer:
B. x=y
Step-by-step explanation:
A 5% tax charge is equivalent to multiply the current price by 1.05. On the other hand, a 5% discount is equivalent to substrace the current the 5% of it, so in the end, you multiply the current price by 0.95.
For X we should multiply first by 0.95, then by 1.05
For Y we multiply first by 1.05, then by 0.95
Hence, if L = price list, we have
- x = L*0.95*1.05 = 0.9975L
- y = L*1.05*0.95 = 0.9975L
- z = L
As a result, x=y<z. Option B is correct.
Note that applying discount first or charging taxes first doesnt matter because the order of the factors doesnt ater the product.
