IlI. The probability that a patient recovers from a rare blood disease is 0.3. If 20 people are known to have contracted this disease, (a) exactly 3 survive; (b) at least 2 survive, (c) the mean and variance of this process. (20 points)
Problem 5: The probability that a patient fully recovers from a severe back pain after a certain type of therapy is 0.85. Suppose 20 people are known to have severe back pain were subjected this type of therapy. (1) Find the probability that exactly 15 fully recover? (2) Find the probability that at least 9 recover? (3) Find the probability that at least 14 but not more than 18 recover? (4) Find the probability that at most 15 recover? (5)...

In a game called heads, a player tosses a coin three times. S/he wins N$300 if 3 heads occur, N$200 if 2 heads occur, and N$100 if 1 head occurs. On the other hand, S/he loses N$1500 if no head occurs. Let Y be a random variable denoting the player's gain (or loss). The coin is biased such that the probability of landing heads up is 2/3. a) Find the probability distribution of Y b) Hence, or otherwise, find the...
29. Suppose it is believed that the probability a patient will die from a certain disease following treatment is 0.1. In a group of 150 such patients, the number who do not die would have mean and standard deviation_ (given to two decimal places).
The probability that a patient fails to recover from a particular operation is 0.2. suppose that seven patients having this operation are selected at random. What is the probability that exactly three patients will not recover? what is the probability that all patients will recover?
In a region, there is a 0.8 probability chance that a randomly selected person of the population has brown eyes. Assume 11 people are randomly selected. Complete parts (a) through (d) below. a. Find the probability that all of the selected people have brown eyes. The probability that all of the 11 selected people have brown eyes is (Round to three decimal places as needed.) b. Find the probability that exactly 10 of the selected people have brown eyes. The...
Q-3: People living in an area have a 30% risk of contracting a deadly disease. Let the X random variable show the number of people who are not infected. In this case, among 20 people randomly selected from this region: 1.P(2< X 9) =? 2. P(3, 206 < X < 10,794) what is the minimum? b) it is known that 0.02 of the products in a factory are defective. By calculating the probability of at least 3 of 100 products...
9. People who have been in contact with a carrier of a disease, have a 40% chance of contracting the disease. Suppose that the carrier of the diseases may have infected a school with 500 people. Find the approximate probability that at least 215 people will contract the disease. A. 0.09 B. 0.91 C. 0.05 D. 0.89
