Question
The letters of the word MISCHIEF are arranged among
themselves. What is the probability that word ICE will be contained?Solution
The letters of the word MISCHIEF can be arranged among themselves in
8!/2! ways.
If ICE is taken together, (ICE) (M) (S) (H) (I) (F)
The number of arrangements that can be made
= 6!/2!
∴ Required probability = (6!/2!)/(8!/2!) = 1/56
√(?) ² = √7396 - √6889
Simplify the following expressions and choose the correct option.
[(7/8 of 256) ÷ 4] + (3/5 of 150) = ?
What will come in the place of question mark (?) in the given expression?
? ÷ (33 - 12 X 2) = (24 + 50 - 38) ÷ ?Â
4.7 × 3.5 + 4.2 × 4.5 = 22.5 × 3.5 - ?
1123 + 1452 + 1015 - 2640 = ?
What will come in the place of question mark (?) in the given expression?
(11/45) of 225 + 3 X 75 = ? X (72 ÷ 6 + 4)
What will come in place of (?) in the given expression.
12.5 + 7.75 - 3.6 = ?3(2/3) of 2(5/11) of 5(2/5) of 75 = ?
(12% of 1250 + 85% of 400) x 10 = ?2
22 + 60 × 3 ÷ 12 = ?
