If 25 people play the game how many people do you expect to hit hhh?

Step-by-step explanation:

To find the answer we must use the diagram, we see that among 8 possible results, there's one possible outcome to hit HHH.

So, to find the amount of people that are expected to hit HHH, we just have to  multiply each percentage assigned to the HHH outcome:

Now, we see that a 10.5% of the people will be expected to hit HHH.

The approximate number of people would be:

Therefore, almost 3 persons are expected to hit HHH.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
