Do you mean (cross-product)?
That is, .
Then yes, that's correct.
Given that set A consists of positive odd numbers less than 100, set B consists of positive even numbers less than 5 and if set C consists of the product of set A and set B. Find the number of numbers possible in set C?
Well, there are 50 positive odd integers below 100 and the even numbers 2 and 4 are below 5 for set B. So the possible number of numbers in C is 100?
