Question 1119460
.
3 balls are to be randomly selected without replacement from an urn containing 20 balls numbered 1-20. 
If we bet that at least one of the balls that are drawn has a number as large than 17. What is the probability that we win the bet?

In English, this combination of words "as large than 17"  is an impossible construction, which is never used and does not carry any sense.
