Need clear steps for each three questions!!

How many even 4-digit numbers greater than 5000 can be formed from the digits 2,4,7,8,9 if no digit can be used more than once? Two digits are to be chosen at random, one after the other, from the ten digits, without repetition, to form a 2-digit number. Let E1 and E2 be the events that the first digit is even and the second digit is even respectively. Express the following probabilities in terms of these events using probability notations and compute them accordingly: (i) both the first and second digits are even (ii) the second digit is odd (iii) one digit is odd 3 people are to be chosen at random from 5 men and 4 women to form a team. Find the probability that the team contains (i) 2 men and 1 woman (ii) at least 1man
