In a school of 330 students, 85 of them are in a drama club, 200 of them are in a sports team and 60 of them do both

Neko [114]

Answer:

105/330 = 21/66 = 7/22

7/22 is the answer I think

Step-by-step explanation:

n(U) = 330

n(A) = 85

n(B) = 200

n(A n B) = 60

Now,

n(A U B) = n(A) + n(B) - n(A n B)

or, n(A U B) = 85 + 200 - 60

or, n(A U B) = 285 - 60 = 225

Now,

n(A U B) compliment = n(U) - n(A U B)

n(A U B) compliment = 330 - 225

so, n(A U B) compliment = 105

Now,

probability = 105/330

When rolling a number cube with sides labeled 1 through 6, what is the probability of rolling a number greater than 2?

vlabodo [156]

That would be 4/6, or 2/3 simplified. As a percent, that would be 66%.

I hope this answer helped you! If you have any further questions or concerns, feel free to ask! :)

Degger [83]

Answer:

$\frac{470}{32-n}$

Step-by-step explanation:

We have been given that there were 32 volunteers to donate blood. Unfortunately, n of the volunteers did not meet the health requirements, so they couldn't donate.

So the number of volunteers that donated blood will be 32-n.

We are also told that the rest of the volunteers donated 470 milliliters each.

To find the units of blood donated by each of the volunteers we will divide total units of donated blood by number of volunteers, who donated the blood (32-n).

$\text{Millimeters of blood donated by each volunteer}=\frac{470}{32-n}$

Therefore, each of the volunteers donated $\frac{470}{32-n}$ millimeters of blood.
