73.5/200 = 36.75/100 = 36.75%
More than 140 rolls will be required if and only if the sum of the first 140 rolls does not exceed 400Let S = X1 + X2 + ... + X140 where Xi is the number obtained in the ith rollNote E[X] = 7/2, Var[X] = 35/12So E[S] = 140(7/2) = 490, Var[S] = 140(35/12) = 1225/3By Central Limit Theorem, (with continuity correction)Pr{S ≤ 400}≈ Pr{Z < (400.5 - 490)/√(1225/3)}≈ 4.731327 * 10^(-6)
25 per cent is a quarter and a quarter of 4 is 1. So a quarter of 400 is 100. Exact answer straight away! No estimation required.

Use the names of operations to convert this to an algebraic equation: "is" means "=" Percent means "/100" (divided by 100) "of" means "*" (multiply) "what number" means to insert your favorite letter for a variable (usually the letter x) 72=18/100 * x 72 = .18x 72/.18 = x 400 = x Mental Check: 10% of 400 is 1/10 of 400 which is 40. 20% of 400 is 2/10 of 400 which is 80. Is 72 larger than 40, less than 80 but closer to 80? Yes. So I think we're at least close. Use your calculator: 18% of 400 or .18 * 400 = 72!!
