Getting two heads in a row does not change the probability of getting a tail. There is a 50/50 chance for both heads and tails each time you flip a coin, because there are two possibilities each equally possible. The 50% probability of getting a tails is not a guarantee. It's possible to get more heads than tails, or vice versa. What the probability means is that on average the results are about equal, and you have an equal likelihood of getting either result.

Mari has spent $18 on startup costs (supplies to make the lemonade cups and advertising)
The break-even point is the point at which the revenue earned just meets the costs
Now, to break-even she needs to make sure she sells lemonade worth at-least $18 on the national lemonade day.
If she manages to make more than $18, then anything beyond $18 would be her profit.
