Question

HELP PLEASE
Choose a number from 1-50 at random. What is the probability that it is either divisible by 5 or divisible by 7?

Answer 1

the answer is 8/25

to get this answer i thought of all of the numbers divisible by 5 or 7 to 50 and i got 16 numbers (5,7,10,14,15,20,21,25,28,30,35,40,42,45,49,50)

i got the fraction of 16/50 then i simplified it to get 8/25 hope this helps
