Question 581895: I have a problem with this problem:
The square letter tiles shown below are placed in an empty box. The tiles are equal in size. 2 B tiles,4 N tiles, 3 R tiles, and 1 O tile.
If two tiles are randomly selected without replacement, what is the probability that the first tile will be the letter R and the second tile will be the letter N?

P(selecting R then selecting N) = P(selecting R AND selecting N)

P(selecting R then selecting N) = P(selecting R)*P(selecting N)

P(selecting R then selecting N) = (3/10)*(4/9)

P(selecting R then selecting N) = 12/90

P(selecting R then selecting N) = 2/15
