A finite math class of 50 students is composed of freshmen and sophomores according to the table below. A student from the class is selected at random. Freshmen Sophomores Females 12 8 Males 14 16 a) What is the probability that the selected student is either a male or a freshman? b) What is the probability that the selected student is neither a female nor a sophomore?
A group of dogs consists of six brown males, two brown females, six white males, four white females, four black males, and six black females. Q1: What is the probability of selecting at random a brown female dog? Q2: What is the conditional probability of selecting at random a black female dog and then a male white dog? Q3: What is the conditional probability of selecting at random a brown dog, if the dog is a female?
A seminar class consists of eight students. Three are males and five are females. A sample of three students is to be selected at random, without replacement, from the class. Let X represent the number of males obtained in the sample. "Then X is a binomial random variable." Is the statement in quotes true or false? True False
A group consists of 18 students, 12 of which are females. If two students are selected at random from the group, one at a time and without replacement, what is the probability that the second student selected is female?
A group consists of 16 students, 6 of which are females. If two students are selected at random from the group, one at a time and without replacement, what is the probability that the second student selected is female? (answer to 4 decimal places)
Suppose 56% of students in the school are male. Also, 7% of the males are Math Majors and 3% of the females are Math Majors. A student is chosen at random and found to be a Math Major. Find the probability that this student is male.
Problem 1: There are 8 males and 12 females in a class. If one student is chosen at random, what is the probability a female student is selected? Problem 2: From the class described in the previous question (8 males, 12 females) how many ways are there to line up 5 students (regardless of gender)? Problem 3:The following college degrees were awarded at a university in a recent academic year: Bachelor’s Master’s Doctorate Men: 307 138 84...
In a population initially consisting of 75% females and 25% males, you are given: i. For a female, the force of mortality is constant and equals μ. ii. For a male, the force of mortality is constant and equals 1.5μ. iii. At the end of 20 years, the population consists of 85% females and 15% males. Answer the following questions, a. Derive an expression in terms of μ of the probability that a female survives 20 years. b. Calculate the...
