A suburban high school has a population of 1376 students. The number of students who participate in sports is 649. The number of
Afina-wow [57]

108 / 1376 is the probability that a student participates in both sports and music.

<u>Step-by-step explanation:</u>

It is given that,

A suburban high school has a population of 1376 students.

  • Let the event A be the no.of students participated in sports.
  • Let the event B be the no.of students participated in music.

The number of students who participate in sports is 649.

The number of students who participate in music is 433.

<u>To find the probability of event A (sports) :</u>

P(sports) = No.of students participated in sports / Total students.

⇒ 649 / 1376

∴ P(A) = 649 / 1376

<u>To find the probability of event B (music) :</u>

P(music) = No.of students participated in music / Total students.

⇒ 433 / 1376

∴ P(B) = 443 / 1376

From the question, we know that the probability that a student participates in either sports or music is 974 /1376.

∴ P(A∪B) = 974 / 1376

<u>To find the probability that a student participates in both sports and music :</u>

The formula used here is,

P(A∩B) = P(A) + P(B) - P(A∪B)

⇒ 649 / 1376 + 433 / 1376 - 974 /1376

⇒ 108 / 1376

∴ P(A∩B) = 108 / 1376

Learning Task 2 A. Complete the Venn diagram. 1. The set of whole numbers from 1 to 15 Set A = all even numbers in this set 2. T
kykrilka [37]

A Venn diagram is used to present the relationship between sets in a logical form

Please find attached the completed Venn diagrams for the questions with the contents outlined as follows;

1. The set of whole numbers 1 to 15 = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}

Set A = All even numbers in this set

Set A = {2, 4, 6, 8, 10, 12}

2. The set of whole numbers from 1 to 20

Set C = All even numbers = {2, 4,  6, 8, 10, 12, 14, 16, 18, 20}

Set D = All multiples of 4 = {4, 8, 12, 16, 20}

3. The set of all whole numbers from 1 to 20

Set E = {2, 4, 6, 7, 9, 10}

Se F = {3, 4, 5, 9, 10, 13, 15, 16, 19,20}

The center of a circle is located at (2, 3) and has a radius of 6 units. Which equation represents this circle?
Helen [10]

By using the general equation for a circle, we will see that the correct option is:

(x - 2)^2 + (y - 3)^2 = 36

<h3>How to find the equation for a circle?</h3>

The general equation for a circle centered at the point (a, b) of radius R is given by:

(x - a)^2 + (y - b)^2 = R^2

In this case, the center is (2, 3) and the radius is R = 6 units, replacing that in the above equation we get:

(x - 2)^2 + (y - 3)^2 = 6^2

(x - 2)^2 + (y - 3)^2 = 36

So the correct option is B.
