Answer» We have the digits, 0, 1, 3, 5 and 6. We need to make a four digit number with no repetition. We have to decide how many numbers we can choose from for each place value. The first place we can only choose from four numbers. Why? Because if we place a zero in the first place value we actually only have a three digit number. So zero cannot be used. That leaves us with 1, 3, 5 and 6. The second place we cannot use the number we used in the first place BUT we can use zero. So again we have four options. The third and fourth place values can only use whatever numbers are left. The counting principle is used for this problem. It tells us to multiply our number of outcomes for each choice to find the final number of outcomes. SO… 4*4*3*2=96 There are 96 possible four digit integers given 0, 1, 3, 5 and 6 with no repitions Like my answer if you find it useful! |
