For the given experiment of spinning a spinner and drawing a card, we will see that:

A) Yes, the events are independent.B) P(3 and A) = 1/16C) P(5 and C) = 0D) P(4) = 1/4     P(B or C) = 1/2E) P(3 and not D) = 3/16

What are independent events?

We say that two events are independent if the outcome of one does not affect the outcome of the other.

In this case, the outcome of the spinner clearly does not affect the outcome of the card draw, so the events are independent.

How to get the probabilities?

B) First we want to get the probability of getting 3 and A.

The probability of getting a 3 when drawing a card is given by the quotient between the numbers of card with the number 3 (only one) and the total number of cards, so we have:

p = 1/4

Similar for the case of the spinner, the letter A appears twice, and there are a total of 8 letters, then the probability is:

q = 2/8 = 1/4

The joint probability is the product of the two individual probabilities, we have:

P(3 and A) = p*q = 1/4*1/4 = 1/16

C) The probability of getting a 5 and the letter C is 0, because there is no card with the number 5.

D) P(4) is the probability of drawing the card with the number 4, this is:

p = 1/4

P(B or C) is the probability of spinning the letter B or C. There are 2 B's and 2 C's, and a total of 8 letters, so the probability is:

q = (2 + 2)/8 = 1/2

E) P(1 and not D) is equal to: P(1 and A or B or C).

P(1) is 1/4.

P(A or B or C) is 6 over 8 (because there are 6 cards that are either an A, a B, or a C)

Then the joint probability is:

P(1 and not D) = (1/4)*(6/8) = 3/16

If X∼U(3,34) follows a uniform distribution, what is the mean and standard deviation of X?

Answers

The mean of the uniform distribution of X is the average of the distribution

The mean and standard deviation of X are 18 and 9.24, respectively

How to determine the mean?

The uniform distribution of X is given as:

X∼U(3,34)

This means that:

a = 3 and b = 34

The mean is calculated as:

[tex]\bar x = \frac{a + b}{2}[/tex]

So, we have:

[tex]\bar x = \frac{2 + 34}{2}[/tex]

[tex]\bar x = \frac{36}{2}[/tex]

Evaluate

[tex]\bar x = 18[/tex]

How to determine the standard deviation?

This is calculated as:

[tex]\sigma = \sqrt{\frac{(b - a)^2}{12}}[/tex]

Substitute known values

[tex]\sigma = \sqrt{\frac{(34 - 2)^2}{12}}[/tex]

Evaluate the exponent

[tex]\sigma = \sqrt{\frac{1024}{12}}[/tex]

Divide

[tex]\sigma = \sqrt{85.33}[/tex]

Evaluate the root

[tex]\sigma = 9.24[/tex]

Hence, the mean and standard deviation of X are 18 and 9.24, respectively

If a function f(x) is vertically translated by k units f(x) becomes f(x)+k where k is positive.

Given function [tex]f(x)=x^3[/tex] is vertically shifted by 4 units
