It would help if you proofread your questions before you posted them. Don't know about a.

If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.

(b) 5/10 *(5-1)/(10-1) * 3/8 = ?

(c) 5/10 * 4/9 * 3/8 * 2/7 = ?
