a company makes 100 bags

35 of the bags have buttons no zips
34 of the bag have zips no buttons
27 of the bags have neither zips or buttons
a bag is selected at random
what is the probablity the bag has buttons?

If there are x bags with both buttons and zips, then

34+35+x = 100-27
P(buttons) = (35+x)/100

35 + 34 + 27 = 96

What happened to the other 4?

35/100 = 7/20

To find the probability that the selected bag has buttons, we need to divide the number of bags with buttons by the total number of bags.

Given information:
Total bags = 100
Bags with buttons = 35

Probability of selecting a bag with buttons = (Number of bags with buttons) / (Total number of bags)

Therefore, the probability that the bag has buttons is:

Probability = (35 bags with buttons) / (100 total bags)

Probability = 35/100

Simplifying the fraction, we get:
Probability = 7/20

So, the probability that the selected bag has buttons is 7/20.
