A glass vase factory recently produced 3 vases that were chipped and 51 vases that were not. Considering this data, how many of the next 18 vases would you expect to be chipped?

At a glass vase factory, 3 out of the last 15 vases produced were chipped.

We can find the probability by using

P(E)= Total number of outcome in E/ Total number of outcome in the sample space.  

The event of getting 3 vases is E = 3 vase

The sample space is given by S = {1,2,3,4…….,13,14,15}

The no. of possible outcome in the Event E is 3 vases and the no. of possible outcome in Space S is 15.

Probability of getting 3 vase is

P(3) =3/15 which is 1/5.

please give brainliest.
