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. 1/30


B. 2/15


C. 1/15


D. 3/10

Answer 1

weird, none of the answers match what I think it is

numbers less than/equal to 5: 1,2,3,4,5
multiples of 7: 7,21,28

so, 8 numbers out of 30, but that's not one of the choices

Answer 2

Maybe 1/30?

Answer 3

or simplify it

Answer 4

8/30 is 4/15 which isn't one of the choices

Answer 5

oh wait

Answer 6

i missed one

Answer 7

multiples of 7: 7,14,21,28

Answer 8

so 9 numbers out of 30

Answer 9

Answer 10

3/10?

Answer 11
