I just solved it and I'm pretty sure its only one solution, I took the bottom equation multiplied it by -3 then i canceled out the equations and got 9. So that would make it C.
Answer:
The probability that the next person will purchase no more than one costume .
Step-by-step explanation:
The data for a single day is s follows:
- 236 visitors purchased no costume.
- 202 visitors purchased exactly one costume.
- 40 visitors purchased more than one costume.
The total number of customers is, <em>N</em> = 236 + 202 + 40 = 478.
Let <em>X</em> denote the number of costumes purchased by the next person.
Compute the probability that the next person will purchase no more than one costume as follows:
Thus, the probability that the next person will purchase no more than one costume .
To evaluate, we need to follow the order of operations. Below are the steps taken in order:
16 * 3 + [(17 - 3) / 2] - 43
16 * 3 + [14 / 2] - 43
16 * 3 + 7 - 43
48 + 7 - 43
55 - 43
12
Therefore the answer is 12.
