Question

14. The figure below shows nine tiles with single-digit numbers painted on them. If xy is the product of the ue of any two tiles selected at random, how many different possible value for xy are there? (a + a)/a * AA. 4B. 7C. 10D.12

Answer 1

All possible products are:

$\begin{gathered} 0\cdot0=0\cdot1=0\cdot2=0\cdot3=0\cdot4=0, \\ \text{1}\cdot2=2,\text{ 1}\cdot3=3,\text{ 1}\cdot4=4, \\ 2\cdot3=6,\text{ 2}\cdot4=8, \\ 3\cdot4=12. \end{gathered}$

Answer: Option B.
