The probability that a randomly selected pigeon gets an incorrect result is; 0.0103
<h3>How to find the Probability?</h3>
We are told that;
1.5% pigeons are infected.
Inaccuracy of the test = 1 - 97% = 3%
1.5% of the pigeons are infected. Thus;
1 - 1.5% = 98.5% pigeons are un-infected.
Inaccuracy of test is 1 - 99% = 1% .
Thus;
0.03 and 0.01 are the probability of an error being made in infected and un-infected respectively.
Meanwhile, probability of infected and un-infected are 0.015 and 0.985 respectively.
Thus, the probability of a randomly chosen person gets an incorrect result = (0.03*0.015) + (0.985*0.01) = 0.0103

Answer:
42 student tickets and 98 adult tickets
Step-by-step explanation:
Let's call the number of student tickets 's' and the number of adult tickets 'a'.
Then, we can write the two equations below:
5s + 8a = 994
a = 2s + 14
Using the value of 'a' from the second equation in the first one, we have:
5s + 8*(2s + 14) = 994
5s + 16s + 112 = 994
21s = 882
s = 42
Now, finding the value of 'a', we have:
a = 2*42 + 14 = 98

Answer:
Step-by-step explanation:
In the figure, all three triangles are similar. By definition, the corresponding sides of similar polygons must be in a constant proportion. Therefore, we can set up the following proportion to solve for 
by dividing corresponding sides:
