Karolina [17]

The probability that he receives an invitation to work in a bank given that he defends his diploma excellently is \mathbf{0. \overline 6}

The known parameters are;

The probability that a graduate of the Faculty of Finance will defend the diploma excellently, P(A) = 0.6

The probability that he will defend perfectly and receive an invitation to work at a bank, P(A∩B) = 0.4

The unknown parameter is;

The probability that the student will receive an invitation from the bank given that the student defend the diploma excellent, \mathbf {P(B \ | \ A)}

The process

\mathbf{ P(B \ | \ A)} is found using the conditional probability formula as follows;

\mathbf {P(B \ | \ A) = \dfrac{P(A \cap B) }{P(A)}}

Plugging in the values, we get;

P(B \ | \ A) = \dfrac{0.4 }{0.6} = \dfrac{2}{3} = 0. \overline 6

The probability that the student will receive an invitation from the bank given that the student defend the diploma excellent, P(B \ | \ A) = \mathbf {0. \overline 6}

Suppose that there were a positive correlation between the variables u and v. If v is 24 when u is 10, which of these is most li
sveta [45]

Answer:

The correct answer is 48, given by option c.

Step-by-step explanation:

This question can be solved by proportions, using a rule of three.

Positive correlation means that the variables are directly proportional, and thus, we apply cross multiplication.

If v is 24 when u is 10, which of these is most likely to be the value of v when u is 20?

24 - 10

x - 20

Applying cross multiplication:

10x = 24*20

Simplifying both sides by 10:

x = 24*2 = 48

The correct answer is 48, given by option c.
