document.write( "Question 581379: I'm not sure which approach is correct for a probability question:
\n" ); document.write( "The letters of the word \"fantastic\" are written on cards and placed in a bag. Two cards are selected (without replacement). What is the probability that \"at\" will be selected. It seems order matters so my first thought was to multiply probabilities of \"a\" [2/9) and \"t\" [2/8] giving me 1/18. Then I thought perhaps I should be counting total eligible letters [4/9] x [3/8] resulting in 1/6. Which is correct? \n" ); document.write( "
