In any case Wye speaks truth. Now at most 2 people speaks truth for 1 question. So case (1) : Wye and Axe speaks truth Probability = 3/5 × 7/20 × (1-5/6) = 7/200 Case (2) : Wye and Zed speaks truth Probability = 3/5 × 5/6 × (1-7/20) = 13/40 Case (3) : only Wye speaks truth Probability = 3/5 × (1-5/6) × (1-7/20) = 13/200 Add the three cases, we get = 7/200+ 13/40+ 13/200 = 7/40
116.90 ÷ (77.81 ÷ 6.06) + 6.32 = (15.12% of ?) ÷ 4.652
[(2/3 of 899.79) + 25% of 500.21] × (√195.77 + 30.03% of 399.79) = ?
180.25 × 14.995 ÷ √26 = ? × 5.985
20% of 80 × 26% of 65 = ?
? = 21.08 + 18.99 × 21.07
13³ + 1.3² + 1.03¹ + 1.003 =?
(11.98% of 449.99) - 3.998 = √?
`[(sqrt(750) xx15.981) -: 54.003]` `xx` ? = 6997.81001
