Question

A company makes 110 bags.

46 of the bags have buttons but no zips.
20 of the bags have zips but no buttons.
39 of the bags have neither zips nor buttons.
A bag is selected at random.
What is the probability that the bag has buttons?​

Answer 1

51/110

Explanation:

No: of bags with buttons but no zips = 46

No: of bags that have both buttons and zipz = 110-(46+20+39) = 5

No: of bags with buttons = 46+ 5 = 51

Total no: of bags = 110

Probabilty = 51/110

I hope im right!!
