Question
In an election, a voter may vote for any number of
candidates not greater than the number to be chosen. There are 8 candidates and 5 members are to be chosen. In how many way can a person vote?Solution
A voter may cast vote for either 1 candidate or 2 candidates or 3 candidates or 4 candidates or 5 candidates out of 8. The voter may cast vote for 1 candidate in 8C1 ways = 8 The voter may cast vote for 2 candidate in 8C2 ways = 28 The voter may cast vote for 3 candidate in 8C3 ways = 56 The voter may cast vote for 4 candidate in 8C4 ways = 70 The voter may cast vote for 5 candidate in 8C5 ways = 56 Total ways = 218
(92.03 + 117.98) ÷ 14.211 = 89.9 – 30.23% of ?
(512) (2/3) × √64 ÷ (512) (1/3) = (64) (?/2) ÷ (2)6
540 ÷ 6 + 25 % of 120 + ? * 8 = 72 * √9
2/5 of 3/4 of 7/9 of 7200 = ?
2222 ÷ 22 + 992 ÷ 16 + 650 ÷ 25 = ?
- Determine the final value of this expression:
(1/5) of {5⁴ - 24 × 14 + 12 × 18 - 10.5 of 10²} 20% of 150 + 30 X 4 = ? X 5
√1369 + √1024 + √841 =(?)2 − 46
{(8× 8 + 3 × 39) - 620 ÷ 20} = ?
