Question
Three dice are rolled simultaneously. What is the number
of possible outcomes in which at least one of the die shows 3?Solution
In a single roll of dice, there are 6 numbers i.e. 1, 2, 3,4,5,6. Total possible outcomes in rolling 3 dices= 6× 6 ×6 = 216 & the cases without showing 3 number (means every dice will show number 1, 2, 4,5,6 only) = 5× 5×5 = 125 So no. of possible outcomes in which at least one of the die shows number 3 = Total Possible outcomes – cases without showing 3 number = 216 – 125 = 91
500% of (121.8 + 16.4 – 28.2) = ? × 2
150% of 84 + ?% of 130 = 230
What will come in the place of question mark (?) in the given expression?
(72 × 4 – 92) ÷ 14 = ?
33 × ?2 – 6 × 5 = 3270
(3500 ÷ √1225) × √(20.25) = ? ÷ 4
What is 12% of 4% of 7% of 2 x 106 ?
Select the correct combination of mathematical signs that can sequentially replace the * signs and balance the given equation.
42 * 7 * 64 * 11 * 6 *4
Find the simplified value of the given expression:
7 of 9 ÷ 3 × 5² + √81 – 14What will come in the place of question mark (?) in the given expression?
(12.09)2 × 5.98 ÷ 26.95 = ? + 25
10% of 100 + 14 = ?% of 120
