Question
A card is drawn randomly from a collection of total face
cards. What is the probability that the drawn card is a jack?Solution
Three face cards (Queen, King, and Jack) are in each of the four suits (Heart, Diamond, Spade, and Club). So, total number of face cards = 4 × 3 = 12 There are 4 jacks one in each suit (Heart, Diamond, Spade, and Club). n(E) =4 Required probability, = 4/12 = 1/3
What will come in the place of question mark (?) in the given expression?
(63 - ?) ÷ 5 + √625 = 19 X (9 - 6)
- What will come in place of (?), in the given expression.
(4² + 6²) × 2 = ? What will come in the place of question mark (?) in the given expression?
(40/25) X 80 - ? = 45% of 300 - 5525.6% of 250 + √? = 119
1220 ÷ 61 ÷ 5 + 450 of 20% - 70 = √ ?
Simplify the expression:
(5x + 15) / (x² + 3x)
What will come in the place of question mark (?) in the given expression?Â
435 ÷ 29 X 792 ÷ 44 = √(? + 14) + 35 + 221 ÷ 17
...192.251 + 326.233 + 125.021 + 19.273 = ?
36% of 640 – 12.5% of 352 + 25% of 640 = ? – 48% of 432
Simplify the following expressions and choose the correct option.
18 * 15 - {3/5 of 250 + 72}
