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. Answer: The probability is 0.2 or 20 %<span>. </span>
