Question
A box contains 4 yellow balls, 5 black balls and 3 white
balls. If two balls are drawn randomly, find the probability that none of them is black or whiteSolution
Required probability = (4 × 3) ÷ (12 × 11) = 12 ÷ 132 = 1/11
29.88% of 3599.90 + 5/12 of 2399.81 – 34.81% of 1200.18 = ?
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
59.978% of 800.315 - 229.95 = ? - 24.95% of 200.15
(`sqrt(224.95)` `xx` `sqrt(440.89)` ) + (`sqrt(783.82)` `xx` `sqrt(440.87)` ) = ? + 150.03% of 120.33 - 139.86% of 1249.88
...√1567.763`xx` √4400 ÷ 326.9827 + 1223.293 = ?
(15.87% of 79.98 + 19.69% of 64.22) × 4.83 = ?
Determine the simplified value of the given mathematical expression.
What value should come in place of question mark (?) in the following question. (You need not to calcualte the exact value)
?/647 = 226/ ?
63.981 + 64.001 + 65.08019 + 63.11112 =?
