Solution:
There are total 4 suits in the deck of 52 playing cards.
♠️:A,2,3,4,5,6,7,8,9,10,J,Q,K
♥️:A,2,3,4,5,6,7,8,9,10,J,Q,K
♥️ :A,2,3,4,5,6,7,8,9,10,J,Q,K
♣️:A,2,3,4,5,6,7,8,9,10,J,Q,K
According to the question all even numbered cards are removed,ie 2,4,6,8,10 are removed from each suit.
Total cards removed:20
Total cards left in the deck : 32
1) probability of getting a face card:
Total face cards(Favourable outcome)= 12
Total outcome:32
let F is the event of drawing a face card
2)A multiple of 3 of Clubs:
Favourable outcome : 3,9
Total outcomes= 32
if C is the event of drawing a card which is
multiple of 3 of clubs, then probability
3) Red multiple of 5:
Favourable outcomes: ♥️5,♥️ 5
if R is the event of drawing a card which is
multiple of 5 of red colour, then probability
4) A prime numbered cards:
Favourable outcome:12
♠️3,5,7
♥️3,5,7
♥️ 3,5,7
♣️3,5,7
if P is the event of drawing a card which is a prime number, then probability
Hope it helps you.
