Answer:
- Probability of a black queen =1/26
- Probability of a red card
=1/2
Step-by-step explanation:
n(s)=52
Probability of a black queen
- n(a)=2
- P(a)=n(a)/n(s)
- P(a)=2/52
- =1/26
Probability of a red card
- n(b)=26
- P(b)=n(b)/n(s)
- =26/52
- =1/2

Answer:
Total number of outcomes = 52
Cards removed = 2+2+2+2 = 8[2 jack, 2 queen, 2 king and 2 aces of red colour]
Remaining number of cards = 52 – 8=44
Total number of outcomes = 44
(i) Favourable outcomes = 2 [There are 2 black queen]
Required probability =
(ii) Favourable outcomes = number of red cards left = 26 – 8=18
Probability for a red card =
(iii) Favourable outcomes = Number of black jacks = 2
Required probability =
(iv) Number of picture cards left =2+2+2 = 6 [jack, queen, King are picture cards]
Required probability =
(v) Honorable cards [ace, jack, queen and king]
No. of honorable cards left = 2+2+2+2=8
Required probability =
