What is probability?

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we have,

There are four (4) colors to choose from.

The number of sample space is equal to 4.

With the condition given in this item, the probability of landing on blue on the first spin is equal to 1/4.

Similarly, the probability of landing on yellow on the second spin is 1/4.

so, we get,

           P = (1/4)(1/4)  

             P = 1/16

Answer: 1/16 is the probability that you land on blue on your first spin and on yellow on your second spin

lunch from home to those who buy it at tuck-shop
is 11:3. If 87 buy their lunch, how many students
are there at the school?​

Answers

Answer:

There are 406 students in the school

Step-by-step explanation:

Let the number of students in the school be x

The total ratio is 11 + 3 = 14

The ratio that buys lunch is represented by 3

3/14 * x = 87

3x = (14 * 87)

x = (14 * 87)/3

x = 406

Michael is writing an article for the school newspaper. He wants to know which subject (math, reading, science, history, or physical education)
is most liked. He is trying to decide who to survey.

Which population sample does NOT produce a biased result?

A. He asks the school’s teachers
B. He asks his friends after school
C. He asks the students in his math class
D. He asks students he meets in the hallways
E. He asks every fifth student arriving at school

Answers

Answer: E is the answer

Step-by-step explanation:

The population sample that does not produce a biased result is when he asks every fifth student arriving at school. The correct option is E.

What is a survey?

Surveys can be used to determine how representative each person's opinions and experiences are.

When conducted properly, surveys offer precise data about people's beliefs and actions that can be utilized to inform significant decisions.

A huge population's characteristics can be described through surveys. No other research methodology can offer such a wide range of capabilities.

This guarantees a more accurate sample to collect focused results from which to draw conclusions and make significant judgments.

Survey bias is when a question is worded or presented in a way that encourages individuals to select one response over another.

The same holds true if your queries are challenging for customers to comprehend and honestly answer.

As, when he asks every fifth student arriving at school, it can lead to an unbiased result.

Thus, the correct option is E.

A card is chosen at random from a standard deck of 52 playing cards. What is the probability that the card chosen is a queen?
A) 4
B) 1/13
C) 1/52
D) 3/52

Answers

Answer:

B) 1/13

Step-by-step explanation:

This is because as we all know there are four different category of cards - spades, clover, heart and diamond.

In each of these category we have 1 Queen so in total we have 4 Queens

Probability of choosing Queen = 4/52

= 1/13

(This is your answer hope it helps :))

The answer would be B because there are 4 queens in a deck of cards. with there being 52 cards in a deck, you divide 4 by 52. If you put that into a fraction it’s 4/52. simplified, its 1/13. therefore, there’s a 1/13 chance on getting a queen
