3. Check that there are three tiles in the box and the number of draws is two. Select the NOTATION tab. The number of permutations is represented by the symbolic notation ,Pr. A. In ,Pr, what does n stand for? Set of n objects B. In ,Pr, what does r stand for? Set of possible permutations C. What does aP2 equal? 23 - 3 x2 - 6 4. Change the Number of tiles to 4. Check that the Number of draws is still set to 2. A. How many choices are there for the first draw? There will be fourchoices B. How many choices are there for the second draw? There will be three choices C. What does 4P2 equal? 4 - 2 ) ! D. How do you calculate this result? = 4 : 3 . 21 = 12 2 2 1 5. Suppose there were 4 tiles and 3 draws. (Do not change the Gizmo yet.) A.
