The probability of the union of two events is the sum of their probability, minus the probability of their interserction:

If we plug the known values into this formula, we have

From which we can deduce

So, the probability of
is a bit less than
, we have to take away all events that belong to B as well:

Answer:
4 1/14
Step-by-step explanation:
2 5/16=57/16
57/16*8/7=57/16 divided by 7/8
57/16*8/7=57/2*7=57/14=4 1/14
Answer:
If you want me to turn it into an equation it's: y=12x-1
Step-by-step explanation:
Well, the slope will always be first and you have to put x after it. The y-intercept is always the starting point on a graph, so it'll be last on the equation.
C is the answer because with this kind of math the answer can be Neg or Postive <span />
Shirts: 3 x 15.50 = 46.50
120 - 46.50 = 73.50 left to spend on shoes
73.50/32.50(cost per pair) = 2.26....so he was able to purchase 2 pairs of shoes.
