Suppose that people who own a Numberkrunch computer for home use will purchase another NumberKrunch with a probability of 0.6 and will switch to a QuickDigit computer with a probability of 0.4. Those who own a QuickDigit will purchase another with probability 0.7 and switch to a NumberKrunch with a probability of 0.3. Find the probability that if a person has a Numberkrunch computer, two computer purchases later he or she will also buy a NumberKrunch computer. The probability is (Type an integer or a decimal) ETTE
Urn 1 contains 4 red and 6 white balls. Urn 2 contains 3 red and 6white balls. A ball is drawn from urn 1 and placed in urn 2. Then a ball is drawn from urn 2. If the ball drawn from urn 2 is red, what is the probability that the ball drawn from urn 1 was red?
Bonnie and Connie are twins with identical purses. Bonnie needs 35 cents to pay for a parking meter. Suppose that Bonnie's purse has 5 quarters, 3 dimes, and 2 nickels while Connie's purse has 2 quarters, 5 dimes, and 3 nickels in it. Not being able to tell the difference between the purses, Connie picks one at random and grabs two coins from it. What is the probability that Bonnie picked her own purse given that she drew out enough change to pay for her parking meter? (Note: Bonnie needs to put in at least 35 cents to pay her parking meter.)

Dubrovsky sits down to a night of gambling with his fellow officers. cach time he stakes u roubles there is a probability r that he will win and receive back 2u roubles (including his stake). At the beginning of the night he has 8000 roubles. If ever he has 256 000 roubles he will marry the beautiful Natasha and retire to his estate in the country. Otherwise, he will commit suicide. He decides to follow one of two courses of action: (i) to stake 1000 roubles each time until the issue is decided; (ii) to stake everything each time until the issue is decided. Advise him (a) if r= 1/4 and (b) if r=3/4. What are the chances of a happy ending in cach case if he follows your advice?
