Three six- facial gestured fair dice are rolled.
What is the probability that on the button two of the dice view the alike deliver set?
Since the first die can be any number, the probability is 6/6.
Then, suppose the second die to have the same face value as the first die, the probability is 1/6.
Since we want exactly two dice having same face value, the third die must show different face value, the probability is 5/6.
In addition, there are shipway to choose two out of three dice to have the same face value.
Hence, the desired probability is:
A bowl contains 10 balls, of which 4 are red and 6 are white. Balls are randomly selected with replacement from the bowl until 4 red balls have been selected. Let be the number of white balls drawn before the fourth red...If you want to get a sound essay, order it on our website: Orderessay
