Answer 1

If we use probability, it might hit once.

If the slot machine hits jackpot 4 out of 315 times, the probability of hitting the jackpot is
`(4)/(315)`.

If we play 40 times, the probability of hitting the jackpot once is
`(4)/(315)*40`, which is approximately 0.51.

So, the slot machine might hit jackpot once if you play it 40 times.
