Assume that if we pick a person at random from a very large group and determine the day of the week on which they were born, there is an equal chance that it is each possibility (Monday, Tuesday, etc.). Suppose seven people are chosen from the group at random. What is the chance that no two persons were born on the same day of the week?
The probability that a student likes Math is 0.7 and the probability that a student likes History is 0.2 . If only 10% of students like both Math and History, what is the probability that a student chosen at random dislikes at least one of them?
In one city, the probability that a person will pass his or her driving test on the first attempt is 0.69. 11 people are selected at random from among those taking their driving test for the first time. What is the probability that among these 11 people, the number passing the test is between 2 and 4 inclusive? 0.0252 0.0213 0.0259 0.0290
In python..
If we want the computer to pick a random number in a given range say to write code for Picking a random element from a list or pick a random card from a deck, flip a coin etc. we can use Random module The Random module contains some very useful functions one of them is randrange() randrange(start, stop) Example from random import randrange for i in range (3): print ("printing a random number using randrange(1, 7)",r andrange(1, 7))...
Assume that on a standardized test of 100 questions, a person has a probability of 80% of answering any particular question correctly. Find the probability of answering between 70 and 80 questions, inclusive. (Assume independence, and round your answer to four decimal places.) P(70 ? X ? 80) =
The probability that a person selected at random from a population will exhibit the symptoms of lung cancer is 0.1. The probability that a person who was found to have the symptoms also has lung cancer is 0.3 and the probability that a person who was found not to have any symptoms also has lung cancer is 0.1. What is the probability that a person has the symptoms, given that they have lung cancer?
Suppose we pick two cards at random from an ordinary 52-card deck. What is the probability that the sum of the values of the two cards (where we count jacks, queens, and kings as 10, and count aces as 1) is at least 4?
The height of a person is a random variable with variance < 5 inches. According to Mr. Chebyshev, how many people do we need to sample to ensure that the sample mean is at most 1 inch away from the distribution mean with probability 2 95%?
Suppose that 62% of people like chocolate ice cream. If you pick two people at random, what is the probability that they both like chocolate ice cream? Give your answer as a decimal (to at least 3 places) or fraction.
Jeri is listening to the songs on a new CD in random order. She will listen to two different songs, and will buy the CD if she likes both of them. Assume there are 10 songs on the CD and that she would like five of them. a) What is the probability that she likes the first song?! b) What is the probability that she likes the second song, given that she liked the first song? c) What is the...
