| (i) In a single throw of a dice, the probability of getting a number greater than 2 is P. |
| (ii) A card is drawn from a deck of 52 cards. The probability of drawing a red card is Q and a face card is R. |
| (iii) A bag contains 2 blue and 3 green marbles, then the probability of drawing red marble S |
A)
P Q R S \[\frac{1}{3}\] \[\frac{11}{26}\] \[\frac{2}{11}\] 1
B)
P Q R S \[\frac{1}{6}\] \[\frac{1}{4}\] \[\frac{3}{11}\] 0
C)
P Q R S \[\frac{2}{3}\] \[\frac{1}{2}\] \[\frac{3}{13}\] 0
D)
P Q R S \[\frac{2}{3}\] \[\frac{1}{2}\] \[\frac{3}{13}\] \[\frac{3}{5}\]
Correct Answer: C
Solution :
(i) Total number of outcomes = 6 Numbers greater than 2 are 3, 4, 5, and 6. Favorable outcomes = 4 \[\therefore \] Required probability \[=\frac{4}{6}=\frac{2}{3}\] (ii) Total number of outcomes = 52 Number of red cards = 26 \[\therefore \] Probability of drawing a red card \[=\frac{26}{52}=\frac{1}{2}\] Number of face cards = 12 \[\therefore \]Probability of drawing a face card \[=\frac{12}{52}=\frac{3}{13}\]. (iii) Since, there is no red marble in the bag, so probability of drawing a red marble is zero.
