point between the pillars and the height of each pillar
33. All jacks, queens and kings are removed from a pack of 52 cards. The remaining cards are well shuffled
and then a card is randomly drawn from it. Find the probability that this card is:
3
(i) a black face card
(ii) a red card
(iii) a black ace
Answer:
1/10
0
1/2
1/20
Step-by-step explanation:
no jack (4)
no king (4)
no queen(4)
so left cards in the deck r =52-12 = 40
now ,
no. of 3 no. card = 4
so probability=4/40=1/10
no. of face card is 0 as all face card r removed
so probability is =0
toral no. of red card is 26
no. of red card left is 26 – 3(jack , king , queen of hearts) – 3(jack , king , queen of daimond) = 20
so probability=20/40=1/2
no. of ace =4 no. of black ace = 2
so probability=2/40=1/20
