Answer:
10.34% probability that you both pick chocolate
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, it is not important if you or your friends picks first. So we use the combinations formula to find the number of desired and total outcomes.
Combinations Formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.

Desired outcomes:
10 are filled with chocolate, and we want to pick 2. So

Total outcomes:
The box has 30 chocolates, and 2 are picked, so:

Probability:

10.34% probability that you both pick chocolate
Step-by-step explanation: x+(x+2)+(x+4)+(x+6)+(x+8)+(x+10)=126
6x+30=126
6x=96
X=16
Since x is the first number , x+6 is the fourth even number .
Thus, the fourth number in the sequence is 22
Answer:
21, 42, 63, 84.
Step-by-step explanation:
The cards with a star and a circle must be multiples of 3 and 7.
So these must also be multiples of 21:
These are 21, 42, 63 and 84.
8 ÷ 544 = 0.0147058824, 544 ÷ 8 = 68
Let's say
a = 215,658
ok... so.. he first lost 1/3 of that

so, his nickname might just be even steven, because, he ended up with the same original amount after the 1/2 bump.
