Answer:
f(-2) = -1
Step-by-step explanation:
Look at x = -2 and find the value of y.
Yes, the question is a statistical question. It anticipates an answer that varies from one individual to the next. The responses will be numeric.
Answer:
The probability mass function is:

Step-by-step explanation:
The people are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability mass of the hypergeometric probability distribution is given by:

In which:
x is the number of successes.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
In this question:
22 + 25 = 47 jurors, so 
22 are women, which means that 
Jury of 12, which means that
.
Thus


Which is the probability mass function.
