Re: Compute the solution:

Hi;

The solutions in 389 are perfect. Excellent, bobbym!

390. Solve for x and y:
2ax + 3by = a + 2b,
3ax + 2by = 2a + b.

Hi NakulG and bobbym,

The solution set in 390 is correct. Excellent, bobbym! Good attempt, NakulG!

391. Two dice are thrown simultaneously. What is the probability that
(i) 5 will not come up on either of them?
(ii) 5 will come up on at least one?
(iii) 5 will come up at both dice?
