15 - 2(- 13s + 3) = 9s - 9 + 16s
15 + 26s - 6 = 25s - 9
9 + 26s = 25s - 9
26s - 25s = -9 - 9
s = - 18
The probability of randomly selecting a cream filled
Chocolate is 1/4
- Probability is the likelihood of an event will occur
- Probability of an event is find out by divide the number of favorable outcomes by the total number of possible outcomes.
- The simplest example is flipping of a coin.
- There are only two possible outcomes when you flip a coin. It wiil be either heads or tails.
- Total probability is always lie between 0 and 1
Let E be the event of selecting cream filled chocolate.
Number of favourable outcome = 6
Total number of possible outcome = 24
Probability if selecting a cream filled chocolate = 6/24
= 1 / 4
Hence, the probability of randomly selecting a cream filled chocolate is 1/4

The formula for finding the sum of a finite geometric series is
![S_n = a_1( \frac{1-r^n}{1-r} )](https://tex.z-dn.net/?f=S_n%20%3D%20a_1%28%20%5Cfrac%7B1-r%5En%7D%7B1-r%7D%20%29)
n = 17,
![a_1 = 3](https://tex.z-dn.net/?f=a_1%20%3D%203)
, r = 2
Substitute into the formula and you get 393213
You have to divide the amount of meters he walked by the time he spent, so 37.5 divided by 3. That equals 12.5 meters per minutes.
Since the angle is positive, you can find any coterminal angle by applying:
Angle + x = 2π ==> 7π/6 + x = 2π ==> x = 2π - 7π/6
x= 12π/6 -7π/6 = 5π/6
So the angle 5π/6 is the coterminal of 7π/6
