The probability that the next person will purchase exactly one costume is 67%.
<h3>How to calculate the probability?</h3>
Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1.
53 visitors purchased no costume.
151 visitors purchased exactly one costume.
22 visitors purchased more than one costume.
Total visitor = 53 + 151 + 22
= 226
Probability that the next person will purchase exactly one costume will be:
= Those with one custome / Total visitors × 100
= 151 / 226 × 100
= 67%
The probability is 67%.

If you have a no solution choice that will be your answer because w+34=w-22
you would subtract w from both sides to get 34=-22 and that's not true therefore it would be a no solution equation.
Answer:
explained
Step-by-step explanation:
(i) Let A be the event that a student takes statistics subject as a major.
Let B be the event a student gets a job.
Two events (or propositions) are mutually exclusive or disjoint if they cannot both occur (be true). A clear example is the set of outcomes of a single coin toss, which can result in either heads or tails, but not both.
In this case, the event A and B are not mutually exclusive.
Therefore, P(A or B) = P(A U B) = P(A) + P(B) − P(A ∩ B)
