The answer is 3C2*4C4*5C2 = [3 * 1 * (5*4)/(2*1)] = 3*1*10 = 30 ways.
Since it must be a 5 digit number, range is the numbers from 20000 to 55555 we will use multiplication rule to figure this out too. If a number is divible by two, its last(ones place) digit is even. If it is divisible by 5 its last(ones place) digit is zero or 5. We don't give a rat's derriere what the other digits are (for divisibility by two or five) The number of ways to choose the ten thousands place digit is 4 the number of ways to choose the thousands place digit is 5 the number of ways to choose the hundreds place digit is 5 the number of ways to choose the tens place digit is 5 The number of ways to choose the ones place digit is FOUR, since it must be 0,2,4,5 and not 3 use multiplication rule and solution is 4 x 5 x 5 x 5 x 4 = 2000
