Cards with the numbers 1 through 50 are placed in a box and thoroughly shuffled. What is the probability of randomly selecting a card with a number less than 10 or a multiple of 12? A. B. C. D.
I think this is correct:
P (>10) = 10/50 = 1/5
P (x12) = 4/50 = 2/25.
hope it helps
there are 9 numbers less than 10
how many others are multiples of 12?
9/50 and 4/50
hope this helps.
