1st card = 13/52
2nd card = 12/51
3rd card = 11/50
4th card = 10/49
5th card = 9/48
13/52 * 12/51 * 11/50 * 10/49 * 9/48 = 33/66640
there are 4 different suits so 4 * 33/66640 = 33/16660
answer is C
Answer:
X=1, -13
Step-by-step explanation:
Answer:
landing on a shaded portion and landing on an even number
; landing on a shaded portion and landing on a number greater than 3
; landing on an unshaded portion and landing on an odd number
; and landing on an unshaded portion and landing on a number less than 2.
Explanation:
Mutually exclusive events are events that cannot occur at the same time. Our spinner has two grey sections, on 1 and 3; and two white sections, on 2 and 4.
This means that the spinner cannot land on a shaded (grey) portion and land on an even number at the same time, since the grey sections are numbered 2 and 4, both of which are even numbers.
The spinner also cannot land on a shaded (grey) portion and land on a number greater than 3 at the same time; this is because the only number greater than 3 on the spinner is 4, which is a white portion.
The spinner cannot land on an unshaded (white) portion and land on an odd number, since the white sections are labeled 2 and 4, which are both even.
The only number on the spinner less than 2 is 1, which is grey; this means the spinner cannot land on a number less than 2 and an unshaded (white) portion at the same time.
The statement second "this is nonresponse bias because many customers may choose to not fill out the cards" would be the best choice.
<h3>What is a survey?</h3>
A survey is a means of gathering information from a sample of people using pertinent questions with the goal of understanding populations as a whole.
We have an automotive service centre would like feedback on its customer service each customer receives a printed card after they pay for services with a short survey on which customer service is ranked on a scale from 1 to 5.
From the data given we can say, not everyone will choose to leave a review when leaving the store, and those who do will have been inconvenienced in some way and felt compelled to do so, while the rest of the customers left and went about their business.
Thus, the statement second "this is nonresponse bias because many customers may choose to not fill out the cards" would be the best choice.

// I am NOT sure about this, but I think it's part to part.
If it was part to whole ratio it will be out of total number of videos.
like ratio of videos that are drama to total videos.....
or ratio of videos that are not drama to total videos.....
You are talking part of each ratio and combining to a different one, so I think it's part to part.
//Again I am not sure about this. But kinda make sense.
