Question 1. In MATH 233 course of this semester, there are 26 students and six of them are women. (a) How many ways are there to select a group of four students from MATH 233 students so that there is at least one women in the group? (b) If I randomly select a group of four, what is the probability that the group has women only? (c) I randomly choose a group of four out of 26 students. Then, again, I choose randomly a group of four from 26 students. What is the probability that these two groups are the same

A math teacher, wanting to assess students 'knowledge, put in a competition in which students' performance averaged 65 (with an excellent 100) and a standard deviation of 10 units. Let's consider that the distribution of performance is normal: A. Find the probability that the performance of a randomly selected student is over 75. B. If we consider that the random variable that describes student performance is continuous (that is, it can take any real value between 0 and 100 and...

Does delaying oral practice hinder learning a foreign language? Researchers randomly assigned 28 beginning students of Russian to begin speaking practice immediately and another 28 to delay speaking for 4 weeks. At the end of the semester both groups took a standard test of comprehension of spoken Russian. Suppose that in the population of all beginning students, the test scores for early speaking vary according to the N(34, 6) distribution and scores for delayed speaking have the N(33, 6) distribution....
