Answer: Our required probability is 0.3387.
Step-by-step explanation:
Since we have given that
Number of red cards = 4
Number of black cards = 5
Number of cards drawn = 5
We need to find the probability of getting exactly three black cards.
Probability of getting a black card =
Probability of getting a red card =
So, using "Binomial distribution", let X be the number of black cards:
Hence, our required probability is 0.3387.
we can use synthetic division
and then we can find quotient
we can see in the image
we will get
so, we get
