Question

25. In many women's tennis matches they play best-out-of-three sets. In other words, they play until one player wins two sets, and there are no ties. Lourdes and Mariana are two rivals, though Lourdes seems to win about six sets for every four that Mariana wins. Use the random numbers table below to simulate 10 matches between Lourdes and Marian. Let an entry in the table correspond to one set, 0-5 corresponds to Lourdes winning the set, and 6-9 corresponds to Mariana winning the set. Begin each match with a different highlighted number, and use it with up to two entries below it to represent a match. In how many of the ten simulated matches needed all three sets? 0 4. 4 9 9 5 2 9 1 0 0 0 A) 4 B)2 C)5 D) 3 co tho following to answer questions 26-27:

I thought the answer was C) 5 but that is incorrect. I am not sure how to find the correct answer.

Answer 1

As i have calculated, the answer would be none of these. As it comes out to be 6. For you, may be you excluded the last case ( the last boxed random number(RN) 3. If you go below two steps, the first RN is 9, go below again 2 steps. Second RN is 2. So there must be another set played as 9 and 2 belongs to two different sets (0,5) and (6,9). As the random number table is finished, start from the beginning i.e from the very first column and go down two steps, it gives 2. So L wins with a 3 sets decision)

Hence total number of 3 steps decision is 5+1=6.

Here is my calculation :

the upper / and lower \ gives first two random number if we move below two steps and the -- sign to the left gives the 3rd random number.

(5,7)., Maniana wiwo ( (0,5)→ Lourdes wins (1) Pahye namm M wima o-1 2-6 3 Wiwo a-30 16
