How to calculate probability?
The given question has concept of conditional probability.
Conditional probability is applied when we have to find the possibility of an event given the another event already occurred.
Conditional probability is calculated by multiplying the probability of the preceding event by the updated probability of the succeeding, or conditional, event.
Here, the first event is selecting the lemonade can and second event is also selecting lemonade can given one lemonade is already selected.
The probability to select 1st lemonade= 7/20
The probability to select 2nd lemonade=6/19
Multiplying them we get:
Probability:7*6/20*19=21/190
Therefore, the probability to select two lemonades is 21/190.
