Using conditional probability, it is found that P(X⏐Y) = 0.
<h3>What is Conditional Probability?</h3>
Conditional probability is the probability of one event happening, considering a previous event. The formula is:

In which:
- P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
- P(A) is the probability of A happening.
In this problem, we have that X and Y are mutually exclusive events, hence
, hence:

Answer:
(b) 0.5431
Step-by-step explanation:
The proportion of adult tickets sold is the ratio of the total number of adult tickets sold to the total number of tickets sold. Those totals are found on the bottom line of the table.
__
proportion = (adult tickets)/(total tickets) = 126/232 ≈ 0.5431
Approximately 0.5431 of the tickets sold were adult tickets.

Answer: Choice C) 11 + 13 + 15 + 17 + ...</h3>
=====================================================
Explanation:
We're adding terms in the form (2n+5)
The first term is when n = 3, so
2n+5 = 2*3+5 = 6+5 = 11
The next term is when n = 4, so
2n+5 = 2*4+5 = 8+5 = 13
The next term is when n = 5, so
2n+5 = 2*5+5 = 10+5 = 15
And so on
This means,

which matches with choice C. The three dots indicates the pattern goes on forever.
-------------------
Choice B does not have these dots, so that's why choice B is not the answer. If we replaced the infinity symbol with 7, then choice B would be the answer.
