Quantity I: The probability of being 2 Red pens and 2 Black pens.
Quantity II: The probability of being 2 Red pens, 1 Green pen & 1 blacks pen.
Quantity I > Quantity II
Quantity I ≥ Quantity II
Quantity II > Quantity I
Quantity II ≥ Quantity I
Quantity I = Quantity II or Relation cannot be established
Solution:
Quantity I. (5C2 * 4C2)/12C4 = 60/495 = 4/33
Quantity II. (5C2 * 4C1 * 3C1)/12C4 = 120/495 = 8/33
Quantity II > Quantity I
Quantity II. (5C2 * 4C1 * 3C1)/12C4 = 120/495 = 8/33
Quantity II > Quantity I
Q7. The difference between Circumference of circle A and diameter is 90 cm. If Radius of Circle B is 7 cm less than circle A then find area of Circle B?
556 cm²
616 cm²
588 cm²
532 cm²
630 cm²
Solution:
Let radius of circle A be r cm
ATQ
2πr – 2r = 90
r = 21 cm
Radius of circle B=14 cm
Area of circle B= 616 cm²
ATQ
2πr – 2r = 90
r = 21 cm
Radius of circle B=14 cm
Area of circle B= 616 cm²
