Please answer entire question Probabilistic Models in Industrial Engineering Problem 2. (a) How many three-digit numbers can be formed from the digits 0, 1, 2, 3, 4, 5, and 6 if each digit can be used only once? (Note: 062 is NOT a legit three-digit number) (b) How many of these are odd numbers? (c) How many are greater than 330?
2) (5pts) A 3-digit number will be formed using the digits 1, 2, 3, 4, 5; using each digit only once. a) How many possible 3-digit numbers are possible? TOTAL: b) Assume three of the digits are randomly chosen and randomly permuted in order to form the 3-digit number. Then each of the possible 3-digit numbers in part a) are equally likely. Find the probability that the 3-digit number ends up being an even number greater than or equal to...

Given the digits 5, 4, 2, 0, 3, 7, 9, 6, 8. How many three-digit number codes can be formed if the hundreds place must be even and the ones place is at least 5? No repition
Selec 3 digits from 0,1,2,...,5 to make a number. Each digit can be used once and the number cannot start from 0. How many possible numbers are there which are greater than 240?
How many 4-digit numbers can be formed using only the digits {1,2,3} if repetition is allowed and the number must contain the digit 3 somewhere. Hint: it may be easier to first count the numbers that don't contain the digit 3.
