Chances of winning with one ticket:

3/100 * 2/99 * 1/98 = 1/161700

Chances of NOT winning with 24 tickets:

(161699/161700)^24 = 0.99985

Therefore, Jack's chances of winning with 24 tickets is: 1 - 0.99985...or 0.00015. That's about a 1 in 6667 chance.

            In my post, I'd like to propose another solution.

We have 100 balls numbered from 1 to 100, inclusively; so we have 100 distinguishable balls. Of them, we can form = = 161700 different triples. Jack's 24 tickets cover 24 such triples - so the probability to win for Jack is = 0.000148 = 0.0148% (approximately). ANSWER
