If he flipped the coin 100 times and got 50 heads, then the answer would be 0.5 (since 50/100 = 1/2 = 0.5). I think you might be mixing theoretical probability with empirical probability. 

In this case, he got 28 heads out of 75 flips 
so 28/75 = 0.373333... where the 3's repeat forever
This rounds to 0.37

That's why the answer is actually choice A

one of the 50 states is chosen at random What is the probability of not choosing a state with the letter N?
gtnhenbr [62]

8 states start with the letter N. Because you’re looking for the amount of states not starting with the letter N, we’ll subtract 8 from 50. Then you’ll put that over the total amount of states. So you should end up with 42/50 which will simplify to 21/25. Hope this helped!

The average value of y=v(x) equals 4 for 1≤x≤6, and equals 5 for 6≤x≤8. what is the average value of v(x) for 1≤x≤8 ?
Tomtit [17]
The average value over the interval is the area under the curve divided by the width of the interval.

Area = 4*(6 -1) +5(8 -6) = 30
Width = 8 - 1 = 7

Average value = 30/7 = 4 2/7
