Question

Cards numbered 1 through 30 are placed in a bag and shuffled. One card is chosen at random. What is the probability of randomly selecting a number less than or equal to 5, or a multiple of 7?

A. 1/15


B. 1/30


C. 3/10


D. 2/15

Answer 1

the answer would be c because 1-5 would give you 5/30 chance and then multiples of 7 would be 7, 14, 21, and 28 which gives you 4/30. If you add those, it is 9/30 which simplifies to 3/10 :)
