Question

A bag contains 26 letters and 9 numerals. Aubrey draws two cards from the bag. What is the probability that she draws 2 numerals?

Answer 1

The probability is 34% because 9/26=.34615384615. The first 2 numbers makes the percentage

Answer 2

Assuming that she does not replace the first card, you have to combine the two probabilities of drawing a numeral, then drawing a numeral again. The probability of drawing a numeral is
`(9)/(35)` or 25.71%. The 35 is a count of all the cards in the bag. The probability that she draws a numeral the second time without replacing the first one is now:
`(8)/(34)` or 23.53%. Multiplying these together gets you:
`(36)/(595)` or 6.05%.
