A pack of cards consist of different number of white, black and red cards. If the probability of choosing a white or red card is 0.6 and the probability of a white or black card is 0.7, what is the probability of choosing each of the cards individually?

Step 1
From the problem, we know that: P(W or R) = P(W) + P(R) = 0.6 P(W or B) = P(W) + P(B) = 0.7 Since the total probability of choosing any card is 1, we can also write: P(W) + P(B) + P(R) = 1 Now we have three equations with three unknowns. We can solve this Show more…

If you choose 5 cards randomly from a deck of 52 cards, what is the probability that two are red and three are black.

You and I are playing a game. You start each round with 11 cards, where five are red, and the rest are black. You randomly select 6 cards (without replacement), and place them face down without looking at the color. Finally, you guess the color of the majority of the cards. What is the probability that you will select the same number of cards of each color? What is the probability that all of the cards you select will be red cards? What is the probability of the majority of cards selected being red?

A deck of cards contains 20 cards: 6 red cards and 14 black cards. 5 cards are drawn randomly without replacement. What is the probability that at least 4 red cards are drawn?
