Please show work as we need to understand how to evaluate the following questions:
1. You play a card game where 2s are considered wild. You are dealt 7 cards - Determine the probability that you did not get dealt a 2.
2. You have a bag with 5 black marbles, 5 white marbles and 5 red marbles . If you make your selections without replacement what is the probability that you select a black marble, a red marble and a white marble from the bag in that order?
3. You have a jar of coins in your kitchen that contains 50 pennies, 30 dimes, 40 nickels and 20 quarters. You reach in and take out three coins - what are the odds that they are all dimes?
4. How many 5 digit numbers will you make using only odd digits and not repeating any of the numbers?
