It would help if you proofread your questions before you posted them. You indicate three tosses with four outcomes.

The probability of any one toss = 1/2

The probability of all/both events occurring = product of the individual events.

If ratio of length to width = 5/3 and width = 63, the length will be > 63.

5/3 = x/63

Solve for x.
