- 5. How many numbers can you make out of the digits 1, 2, 3, 4, 6 if the rule is that every digit has to be larger than the digit preceding it? For example 124 is ok, 122 is not ok. Every digit can be used only once, but you do not have to use every digit. A tree might help.arrow_forward5 plsarrow_forward8 pls show workarrow_forward
