(a)

different possibilities
(b)


So, there is a 1 in 4 chance that both dice will show an even.
The person above me is right!! I kinda got confused because i thought it was asking what sea level is the diver now BUT its asking for the elevation, so you need to subtract.
Substitute
, so that
. Then the ODE is equivalent to

which is separable as

Split the left side into partial fractions,

so that integrating both sides is trivial and we get








Given the initial condition
, we find

so that the ODE has the particular solution,

If you want to check if your answer is correct, expanding it all out will help!
(x-6)(x+2)=0 <-- Use FOIL tactic
x²+2x-6x-12=0
x²-4x-12=0
As you can see, this is identical to the initial equation given. The x values would be 6 and -2, as seen from the factored equation.
Hope I helped :)
