Question

Imagine you're at the beach. You're really thirsty and decide to go to a beach stand to get some coke. When you arrive, you see there's a queue consisting of one girl and two boys. Unfortunately, the stand has only one coke left. You've learned that six in ten girls drink coke and 30 percent of boys drink coke.

How likely is it that you will get the coke?

Answer 1

Answer:

19.6%

Step-by-step explanation:

6 in 10 girls drink coke which means there is a 60% probability that she will get the coke , hence a 40% probability of you getting the coke .

Now Let's assume we were lucky and the girls didn't take the coke then again there is a 30% probability of you not getting the coke therefore 70% chances of you getting the coke again.

Therefore the total probability of you getting the coke should be 70% of 40 is

28 and there is a boy again therefore again 70% chances of you getting the coke ,therefore 70% of 28 that is 19.6%

I'm not 100% sure if that 19.6% is the answer.
