Which relation is a function?

dimulka [17.4K]

The definition of a function is that for each input, there is only one output. Thus, the answer to your question is A, as it is the only answer option that each input has only one output. In answer choice B, the input -1 has outputs of both -2 and -5. In answer choice C, the input 4 has outputs of both 3 and 0. Finally, in answer choice D, the input -4 has outputs of both -4 and 4. Therefore, answer A is the only function because it is the only option that follows the definition. Hope this helps! :)

A college student is taking two courses. The probability she passes the first course is 0.67. The probability she passes the sec

andrezito [222]

Answer:

0.58 = 58% probability she passes both courses

Step-by-step explanation:

We can solve this question treating the probabilities as a Venn set.

I am going to say that:

Event A: She passes the first course.

Event B: She passes the second course.

The probability she passes the first course is 0.67.

This means that $P(A) = 0.67$

The probability she passes the second course is 0.7.

This means that $P(B) = 0.7$

The probability she passes at least one of the courses is 0.79.

This means that $P(A \cup B) = 0.79$

a. What is the probability she passes both courses

This is $P(A \cap B)$ .

We use the following relation:

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

So

$P(A \cap B) = P(A) + P(B) - P(A \cup B) = 0.67 + 0.7 - 0.79 = 0.58$

0.58 = 58% probability she passes both courses
