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? https://www.dropbox.com/s/n43kflbepqbgbdm/Screenshot%202015-06-16%2018.54.18.png?dl=0

    9 out of 30 total is your answer, or as a fraction \[\frac{9}{30}\] which you probably want to reduce
