Answer:
The number of times a drink must be chosen in order to get each type is:
10
Explanation:
It is given that:
a cooler contains 5 bottles of lemonade 4 bottles of water and 3 bottles of juice.
Now we have to choose the maximum number of bottles such that we have got a drink of each type.
Let us suppose at the first 9 draws we did not get any bottle of juice and only got all the bottles of lemonade and water.
Since we know that the sum of 5+4=9
after which at the tenth draw we will definitely get a bottle of juice since all the other drinks were chosen in the previous draw.
