A board game has 25 cards, each printed with a number from 1 through 25. Sameer shuffled the cards, and then selected 1 card.

What is the probability that Sameer selected a card with a number less than 4 or a multiple of 9? Express your answer in simplest form.

Total number of cards = 25 .
Total number of possible draws = 25
Number of possible successes = 5

(The successful draws are 1, 2, 3, 9, and 18.)

Probability of success = 5/25  =  1/5  =  0.2  =  20%
