The cards are well shuffled and you randomly draw one card.B= card drawn is blue0 = card drawn is odd numberedA. How many elements are there in the sample space ? ____B . P(B) = _____

In a class there are 4 students who are 19 years old and obtained 80 pints in the midterm. There are 6 students who are 19 years old and obtained 50 pints in the midterm. There are 6 students who are 20 years old and obtained 80 pints in the midterm. There are n students who are 20 years old and obtained 50 pints in the midterm. There are no other students. We randomly pick a student in the class, let their age be X and their score by Y. If we are given that X, Y are independent random variables, then compute n.

Suppose that you have 10 cards. 3 are blue and 7 are orange. The 3 blue cards are numbered 1,2, and 3. The 7 orange cards are numbered 1, 2, 3, 4, 5, 6, and 7. The cards are well shuffled. You randomly draw one card. • B = card drawn is blue • O = card drawn is odd-numbered How many elements are there in the sample space?
