MAT 157-CheckPoint Template Student Name: Week #: 2 Instructions: For each assigned problem type in the page number, problem number, and complete solution, showing all work for each problem (using either MathType or Equation Editor recommended) in order to receive credit. One problem in each row, please. Save as a Word file and post to your Individual Forum as an ATTACHMENT. Page # Prob # Complete Solution 505 2 The set S = { m , a , t , h , e , i , c , s } is the sample space of equally likely outcomes. So Prob ( E ) = 4/8 = 1/2. 6 For event E = {2, 3, 4, 6}, Prob ( E ) = 4/6 = 2/3. 12 The probability of drawing a card that is a K or an S is (4 + 13 – l)/52 = 16/52. The chances of drawing a card that is not a K or an S is 1 – 16/52 = 36/52 or 9/13. This complimentary event is logically equivalent to drawing a card that is not a K and not an S : that is not ( K or S ) = (not K ) and (not S ). 18
