5
-- chance
9
you gotta count up all the possibilies (which is 9) then count up all the possible chances there is a rock (which is 5) and put it into fraction form. and there's your probability
A. b(d) = 3.80(12) + 29d +13.95d = 45.60 + 42.95d
B. b(9) = 45.60 + 42.95 (9) = $ 432.12

Answer:
No.
Step-by-step explanation:
No, Bob is not correct.
The formula he's using is the following:

The important thing here is that the angle is between the two sides.
In the given triangle, 120 is not between 8 and 18. Therefore, using this formula will not be valid.
Either Bob needs to find the other side first or find the angle between 8 and 18.
