Answer:
40 people who don't like any of the three drinks.
Step-by-step explanation:
It is given there are 340 people in total
Number of people like tea=150
Number of people like tea only =90
Number of people like coffee only =80
Number of people like milk only =70
Number of people like coffee and milk only = 0
We can draw Venn diagram which helps us to find the number of people who don't like any of these three drinks. I'll attach the file.

16/81
Step-by-step explanation:
As the tile is taken and then replaced this means that the probability of the second event is not impacted by the probability of the first (they are independent)
As there are 9 tiles and 4 of them are even, the probability that the first tile drawn is even is 4/9.
There are still 9 tiles and still 4 of them are even for the second tile being drawn so this probability is then also 4/9.
If we want to find the probability of both events we should multiply together these two independent probabilities.
So:
