In a medical research class the students were asked to find out the time of their birth. of the 38 students in the class, 18 were born between 12 am and 11:59 am. If we pick 5 students at random: a) create a probability distributions for the number of students born between 12 am and 11:59 am (A) (label columns and rows; use only what you need; show work-some or all) b) what is the probability of having 2 or...
In a small class of 5 students, what's the probability of 2 students who share the same birth month while the other 3 students have a unique birth month?
There are 36 students enrolled in this class. What is the probability that at least two of the students have the same birthday? (Ignore the possibility that someone might have been born on Feb. 29.)
In a statistics class there are 12 students. Five of the students are seniors and the rest are juniors. Four students are randomly chosen at the same time from the students in the class to lead four study groups of three students each. What is the probability that the sample of four contains an equal number of seniors and juniors The probability of a person being born with six fingers (polydactyly) is one in five-hundred. If two unrelated people are...
1) Three students are randomly chosen from a school with 800 students (200 students each in grades 9, 10, 11, and 12). Find the probability of each event. a. All were in different grades. b. At least two people were in the same grade.
. Consider your class of 29 students. Calculate the probability that at least two students have the same birthday. For this purpose, assume each day of the year is represented by a box, and we place the name of the student in the box corresponding to their birthday. (a) List total number of possible arrangements. (b) List total number of arrangements that do not have two names in the same box. Obtain the probability that no two students have the...
Dr. Campbell's MLA class has 15 students. All of the students know each other well, and each knows exactly what day of the week they were born on. What is the minimum number of students Dr. Campbell needs to randomly select to guarantee she has chosen two who were born on the same day? (Assume Dr. Campbell is not privy to their birthday information.)
