Probability Question

It is known that 4 tickets among 10 tickets can win the jackpot. Now everyone is permitted to buy a ticket. Find the probability that,
a. Among the 1st 3 persons who bought a ticket, only one person will win the
jackpot
b.The 2nd person who bought tickets will win the jackpot

Are these simply binomial distribution questions?

a. I got 0.432
b. Is it same as P(not winning)*P(wins)*___*P(not winning)?

Always struggle on these types of questions.
Thanks,
M

The numbers are small so I'd not bother with binomial - is this GCSE or AS?
