Answer:
The probability that the first card will be a diamond, the second card will be a black card, and the third card will be a queen is 0.0096
Step-by-step explanation:
Total no. of cards = 52
No. of diamond cards = 13
No. of black cards = 26
No. of queens = 4
Three cards are drawn with replacement from a standard deck.
We are supposed to find he probability that the first card will be a diamond, the second card will be a black card, and the third card will be a queen
Probability of getting diamond card =
Probability of getting black card =
Probability of queen =
Probability that the first card will be a diamond, the second card will be a black card, and the third card will be a queen =
Hence the probability that the first card will be a diamond, the second card will be a black card, and the third card will be a queen is 0.0096
