Question
Two dice are thrown and the sum of the number is noted.
The number of ways in which the sum can be 7 isÂSolution
When two six-sided dice are thrown, there is a total of 6 × 6 = 36 6×6=36 possible outcomes, as each die has six faces numbered from 1 to 6. To find the number of ways to get a sum of 7, we can list all the possible combinations that result in a sum of 7: (1, 6) (2, 5) (3, 4) (4, 3) (5, 2) (6, 1) There are 6 ways to get a sum of 7. Therefore, the answer is 6. Â
40.5 ÷ [4/5 of (32 + 18) - 29/2] = ? ÷ 102
(1/2) – (3/5) + 3(1/3) = ? + (5/6)
(350/?) = 23 + 33
25% of 250 + 32% of 200 = ? ÷ √ 16
? = 20% of 1200 + 256
21% of 400 − 150 = ? − 77
172Â - 92Â + 121 - 74 = ?
24% of 150% of 500 + 140 = ? × 8Â
(22² × 8²) ÷ (92.4 ÷ 4.2) =? × 32
? = 65% of 40% of (20 × 250) − 200
