Answer: 1/5
Explanation:
There are 10 slips of paper.
The only numbers less than three are 1 and 2
The probability that he will pick up a slip of paper less than three is 2 since only 1 and 2 are less than three.
Therefore the probability is 2/10, and when simplified, it is 1/5.
Therefore the answer is 1/5.
