Joel has 8 white golf balls and 7 orange golf balls in a bag. If he removes an orange golf ball and does NOT return it to the bag, what is the probability that the next golf ball he randomly picks from the bag will be white?

57.14%

Step-by-step explanation:

So if he removes an orange ball from the bag, that means there are 8 white golf balls and 6 orange golf balls - 14 balls in total

8 balls of the 14 are white, so to find the percent we can set up a proportion

8/14=x/100

you can simplify 8/14 to 4/7

4/7=x/100

cross multiply

7x=400

divide by 7 on both sides

x=57.14%

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
