Answer:
= 72a + 20s
Step-by-step explanation:
Given that;
a = number of adult tickets sold
s = number of student tickets sold.
According to given condition:
For first night;
=2(9a) + 5s
=18a + 5s
For second night:
= 3*18a + 3*5s

This is what is known as a derangement - an arrangement in which none of the objects maintain their original position.
For example, with the numbers, 1234, in how many ways can they be arranged so that 1 is NOT in first position, 2 is NOT in second position, etc.
Of the 24 possible permutations of four numbers, there are nine possible derangements:
<span><span>2143 2341 2413
3142 3412 3421
4123 4312 4321</span>
So, the probability that no one gets their own trumpet is
9 out of 24 = 3/8 answer is A
