mr. larsen's third grade class has 22 students, 12 girls and 10 boys. two students must be selected at random to be in the fall
faust18 [17]

The probability that no boys will be chosen is 0.2857

What is probability?

The area of arithmetic called likelihood deals with numerical representations of the chance that an incident can occur or that a press release is true.

Main Body:

Total students =22

total boys = 10

total girls =12

Now we have to chose 2 girls from 12 , so combination is used to select ,

⇒¹²C₂

Also, We have to chose 2 girls from 22 students

so it can be represented as ,

⇒²²C₂

Probability of choosing 2 girls = ¹²C₂/²²C₂

On solving this we will get = 0.2857

Hence the probability is 0.2857

Julli [10]

Answer:

16

Step-by-step explanation:

Adam is building birdhouses that requires \frac{1}{2} i.e 0.5 feet long boards.

Now, he has an 8\dfrac{1}{4} i.e. 8.25 feet longboard and wants to cut each 0.5 feet longboards.

We have to calculate the number of pieces of exactly 0.5 feet length that can be made from this 8.25 feet longboard.

Now, \frac{8.25}{0.5}= 16.5

So, there can be 16 whole board of exact length 0.5 feet. (Answer)
