Answer:
Let x be 1, 2, 3 or 4 and y be 1, 4, 9 or 16. Now, \[xy=\{1,4,9,16,2,8,18,32,3,12,27,48,4,16,36,64\}\] Total number of possible outcomes \[=16\] Number of outcomes where product is less than \[16=8\] i.e., \[\{1,4,9,2,8,3,12,4\}\] \[\therefore \] Required probability \[=\frac{8}{16}=\frac{1}{2}\]
