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 .
We know that y is equal to x-2. We can just substitute x-2 for y since y is equal to it.
10x- 9(x-2)=24
Distribute.
10x- 9x+18= 24
x+18= 24
Subtract 18 on both sides.
x= 6
Now, plug in x.
y= (6)-2
y= 4
We can check this to see if this works:
4= 6-2, 4=4
10(6)- 9(4)= 24
60-36= 24, 24=24
x=6 and y=4
I hope this helps!
