Answer:
D. 0.821
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The combinations formula is important to solve this question:
is the number of different combinations of x objects from a set of n elements, given by the following formula.

Desired outcomes
The order is not important. For example, Elisa, Laura and Roze is the same outcome as Roze, Elisa and Laura. This is why we use the combinations formula.
At least 3 girls.
3 girls
3 girls from a set of 5 and 2 boys from a set of 3. So

4 girls
4 girls from a set of 5 and 1 boy from a set of 3. So

5 girls
5 girls from a set of 5


Total outcomes
5 from a set of 8. So

Probability

So the correct answer is:
D. 0.821
Obviously if you wanna know this and do by yourself next time, it's pretty easy an hour is equal to 60 min so if you wanna know how many min are in hours js multiply by 60 for your question of now 3hours×60min=180mi+130=210min
To write and equation we call y=oil and x=vinager, so:

To find the constant k we can use the point in the picture (vinager, oil) = (x, y) = (1, 1.5), so:

So, the equation is:

Now, the meaning of the point (1, 1.5) is for 1 amount of vinager you need 1.5 amount of oil.
