The board game Scrabble® contains 100 tiles, 98 of which are labeled with a letter and a point value, and 2 blank tiles. The distribution of tiles and point values is shown in the table. A tile is drawn at random. Find the probability of each event. (Enter your probabilities as fractions.)


(c) Drawing a tile that is worth 0 points 



I thought it was 2/0 or 0/2 but I am completely wrong can someone help me with this fraction question.

there are 2 0 point tiles out of 100


thus the probability of choosing a 0 point tile is 2/100 = 1/50


similarly there are 10 4 point tiles so the probability of choosing one is 10/100 = 1/10


there are 2 tiles worth 10 points and again the probability is 2/100=1/50 of choosing a 10 point tile


the probability of choosing a tile worth at least 4 point is that of choosing either a 4, 5, 8, or 10 point tile.


I leave you to figure out what that probability is.  (Hint: sum the number of tiles 4 points and greater)
