Question
What is the Probability of getting a sum of
‘9’ on rolling a dice twice?Solution
Now, the concerned events should have sum of ‘9’ i.e., number on Dice 1 + number on Dice 2 = 9 This can be seen in three cases: (3,6) , (6,3) , (4,5) , (5,4) So Concerned events = 4 And, we know total events are always ‘36’ So, Probability = 4/36= 1/9
What should come in place of (?) question mark in the given expression.
(576 ÷ 12) + (3³ × 4) = ?
- 60% of 180 – 30% of 60 = 15% of ?
What will come in the place of question mark (?) in the given expression?
(252 + 198) ÷ ? + 126 ÷ 3 = 144 ÷ 2
- Find the simplified value of following expression:
0.998 + 0.882 + 0.12 √529 + √64 + 92 = ?
What will come in the place of question mark (?) in the given expression?
? = (20 × 62 – 342 )
What will come in the place of question mark (?) in the given expression?
(√1024 + √324)% of 780 = ?% of 260
15848 ÷ 4 – 793 × 6 + 3628 = 3 × ?
{(5/8) + (4/5)} × (?/19) = 33
