Question 7 A bag contains cards numbered from 1 to 25. A card is drawn at random from the bag. The probability that the number on this card is divisible by both 2 and 3 is: (a) 1/5 (b) 3/25 (c) 4/25 (d) 2/25Total numbers = 25 Numbers divisible by both 2 and 3 = Numbers divisible by 6 = 6, 12, 18, 24, 30, 36, 42, โ€ฆ. Number of numbers divisible by both 2 and 3, less than 25 = 4 Thus, P(number divisible by both 2 and 3) = (๐‘๐‘ข๐‘š๐‘๐‘’๐‘Ÿ ๐‘œ๐‘“ ๐‘›๐‘ข๐‘š๐‘๐‘’๐‘Ÿ๐‘  ๐‘‘๐‘–๐‘ฃ๐‘–๐‘ ๐‘๐‘™๐‘’ ๐‘๐‘ฆ ๐‘๐‘œ๐‘กโ„Ž 2 ๐‘Ž๐‘›๐‘‘ 3)/(๐‘‡๐‘œ๐‘ก๐‘Ž๐‘™ ๐‘›๐‘ข๐‘š๐‘๐‘’๐‘Ÿ๐‘ ) = ๐Ÿ’/๐Ÿ๐Ÿ“ So, the correct answer is (c)
