3/6 possible out comes for heads and tails
Answer:
Y=3
Step-by-step explanation:
You go over to the X axis, find -2 and go up the line vertically until you touch the black line going across. You look to the right and see it says 3. So 3 is your answer
So firstly, I'm going to be converting the mixed number into an improper fraction. To do this, multiply the whole number by the denominator and then add that product with the numerator and that will be your new numerator. In this case:
3 × 8 = 24, 24 + 3 = 27. 
Now since they have the same denominator, you can subtract the numerators.

Now simplify the number as such:

<u>In short, your answer is -17/4, or -4 1/4.</u>
