Question

All the three face cards of spades are removed from a well shuffled pack of 52 cards . A card is drawn at random from the remaining pack . find the probability of getting (a) a black faced card (b) a queen (c) a black card (d) a spade

Answer 1

if 3 face cards of spades are removed

no of total possible outcomes = 52-3=49
1)a black faces card=E

no of favourable outcomes = 3
p(E)=no of favourable outcomes/no of total possible outcomes

=3/49
2)a queen=E
no of favourable outcomes=3
p(E)= 3/49
3)a black card=E
no of favourable outcomes=26-3=23
p(E)=23/49
4)a spade=E
no of favourable outcomes=13-3=10
p(E)=10/49

Answer 2

Answer:

(1) 3/49

(2) 3/49

(3) 23/49

step by step explanation:

Total number of outcomes = 52

Total number of possible outcomes = 52-3

= 49 cards

(1) n(s) = 3

P(a black face card) = 3/49

(2) n(s) = 3

P(a queen) = 3/49

(3) n(s) = 26-3

= 23

P (a black card) = 23/49
