The probability of rolling a 6 on the 1st roll is 
, since there is only 1 out of 6 sides of the dice that has six pips.
The probability of rolling an odd number is
, since there are 3 out of 6 sides of the dice that has an odd number of pips. 
Then the probablity of both events happening one after another is
. You have to multiply both probabilities of the events: 
The probability of rolling an odd number is

Answer:
- 0.25|h -1600| -400
- 1000
- 2200
Step-by-step explanation:
Once again, you can choose the correct equation by finding the one that gives d=0 for h=0. (Note that the problem statement requires the independent variable to be h, not x.)
Then you can use that equation to find h for d=-250:
-250 = 0.25|h -1600| -400
150 = 0.25|h -1600|
600 = |h -1600|
This resolves to two equations:
- -600 = h -1600 . . . ⇒ . . . h = 1000
- 600 = h -1600 . . . ⇒ . . . h = 2200

Or, you can realize the distance from the west end is 4 times the depth. At a depth of 250 ft, that distance is h=1000 ft. That is 600 ft from the center, so 1200 ft from the same depth on the other side of the crater, which is at h=2200 ft.
