Answer:
Final answer is 1/8.
Explanation:
Total number cards in deck of cards = 52
Total number of cards with a letter = 16
Total number of cards with red King and letter both = 2
Then probability of getting card with letter P(L) = 16/52
Then probability of getting card with letter and king both P(K and L) = 2/52
Then required compound probability P(K|L) is given by formula:
P(K and L)= P(L)*P(K|L)
2/52= 16/52*P(K|L)
(2/52)*(52/16)=P(K|L)
2/16=P(K|L)
1/8=P(K|L)
Hence final answer is 1/8.
