Aboard 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.

We have to find the probability that one randomly selected card has a number less than 4 or a multiple of 9. There are numbers : 1 - 25. Numbers less than 4 are: 1, 2, and 3. Multiples of 9 that are less than 25 are : 9 ( 9 * 1 ) and 18 ( 9 * 2 ). So there are 5 favourable outcomes and 25 possible outcomes. The probability is: P ( A ) = ( number of favourable outcomes ) / ( number of possible outcomes ) = 5 / 25 = 1 / 5 = 0.2. The probability is 0.2 or 20 %.
