Question

There is a spinner with 14 equal areas, numbered 1 through 14. If the spinner is spun one time, what is the probability that the result is a multiple of 5 or a multiple of 2?

Answer 1

multiples of 5 are A{5,10}
multiples of 2 are B{2,4,6,8,10,12,14}

Multiples of 2 OR 5 are {2,4,5,6,8,10,12,14} for 8 possible outcomes.

Therefore the probability of spinning a multiple of 2 or 5
P(2x or 5x)=8/14 = 4/7
