If the class contains 11 boys and 14 girls, what is the probability of calling on a girl?
Ronch [10]

Answer: P (girl) = 14 / 25

Concept:

Here, we need to know the idea of probability.  

Probability is a measure of the likelihood of an event to occur.  

If you are still confused, please refer to the attachment below for a graphical explanation.

Solve:

Number of boys = 11

Number of girls = 14

Total number of people = 11 + 14 = 25

P (girl) = Favorable / Total (refer to the attachment)

P (girl) = 14 / 25

Hope this helps!! :)

Answer 1-6 (about square root)
Taya2010 [7]

Answer:

1. For a cube, volume = edge^{3}

2. \sqrt[3]{volume} = edge

3. Volume of the cube = 216 so, the edge = \sqrt[3]{216} = 6

4. 1st blank = 6

   2nd blank = 6

   3rd blank = 216

   4th blank = 216

5. 6 is the edge

6. As the room is a square and we have to find the side

Area = 121

Edge = \sqrt[2]{121} = 11

If my answer helped, kindly mark me as the brainliest!!

Thank You!!
