Question
What will be the probability of choosing one red and
one green ball from a basket containing 4 red and 5 green balls if two balls are drawn randomly?Solution
Required probability = (4C1 × 5C1)/9C2 = (4 × 5)/(9 × 4) => 5/9
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 =?
7.898 × ? + 139.89` ` `-:` 14.23 = 4004.04 – 353.89
