Probability of getting a 2 on a fair dice is 1/6 because there are 6 sides on a dice and they’re asking what is the chance of it landing on a specific *1*.
The probability of flipping a head on a coin is 1/2 because there are two sides on a coin and it’s asking what is the chance of it landing on *1* of them.
1/2*1/6= 1/12.

The correct question is:
What is the probability that 2 girls and 2 boys will be selected?

Solution:
Total number of students = 10
Ways to select a team of 4 students = 10C4 = 210

2 Boys can be selected from 6 boys in ways = 6C2 = 15
2 Girls can be selected from 4 girls in ways = 4C2 = 6

Number of ways to select 2 boys and 2 girls = 15 x 6 = 90

Probability of choosing 2 boys and 2 girls = 90/210 = 3/7

Thus, if 4 team members are selected, the probability of choosing 2 boys and 2 girls will be 3/7

Unit 11: Volume and Surface Area Homework 1: Area of Plane Figures- Find Area.
uysha [10]

Answer:

4. 432 cm^2/2 = 216 cm^2

6. 309.76 mm^2

8. pi * 22^2 = 484pi (or, approximately 1,519.76) in^2

484/2 = 242pi or 759.88 in^2.

10. 297.84 in^2/2 = 148.92 in^2

Step-by-step explanation:

To find the area of a triangle, you take the base and multiply by the height, and then divide by 2. Hence giving me the answers I obtained in #4 and #10.

A square is equal on all sides, so you would just square the measurement of the one side.

To find the area of a circle, you would do pi times the radius^2. Since this is a semicircle, you actually should divide the number you got by 2. (Which is why I did so up above).

I hope this helps!
