Fair dice are rolled and the numbers that appear are added. What is the probability that this sum is at least 5?
A fair coin is flipped three times. What is the probability of seeing heads exactly once?
A fair coin is flipped three times. What is the probability of seeing heads at least once?
The Sum Rule states that the sum of the probabilities of all instances of a random variable equals
Two fair dice are rolled and the numbers that appear are added. What is the probability that this sum is exactly 3?
Let set A = {1, 2, 3, 4} and set B = {2, 3, 5, 7}. One number is chosen at random from each set and their sum is calculated. What is the probability that this sum is exactly 6?
Let set A = {1, 2, 3, 4} and set B = {2, 3, 5, 7}. One number is chosen at random from each set and their sum is calculated. What is the probability that this sum is less than 6?
If fair coin is tossed twice, what is the possibility of seeing heads exactly once?
In a valid probability distribution, the probabilities must:
