A bag of coins contain 2 quarters, 3 dimes and 4 pennies probability drawing a dime and then quarter without replacements

2 quarters, 3 dimes, 4 pennies ... total of 9 coins

probability of first drawing a dime = 3/9 reduces to 1/3

without replacement (means u have only 8 coins now)

probability of then drawing a quarter = 2/8 reduces to 1/4

probability of both : 1/3 * 1/4 = 1/12 or 8.3%
