He should guess about 34 times.
When you are rolling two dice there are 36 probabilities. In order to get an 8, there are 5 possibilities.
2 + 6, 3 + 5, 4 + 4, 5, + 3, 6 + 2
Therefore, the chances of an 8 are 5/36. Multiplying this by 250 gives us about 34.
The law of large numbers helps because it says the more rolls that take place, the more likely we are to get close to the expected value. With 250 rolls we should get pretty close.

Answer:
the third one...............
32.3cm (nearly 13 inches) (12.9 inches)
2.5cm = 1 inch. To figure out what 3 quarters ( 3/4 ) of an inch is, divide 2.5 by 4 then multiply by 3. ( 2.5/4 x3 ) This equals 1.9cm. There are 17 blocks so multiply 1.9 by 17. ( 1.9/17 = 32.3) 30 cm = 12 inches. 2.3 is 90% of 2.5, so add 0.9 to 12.
