Answer: The answer to this question is true.
In order to do that you need to do multiplication so for the first person to be chosen there are a total of 12 people so you start with 12 in your equation
then you have 11 people left for the second person so your equation becomes 12x11
there are 10 people for the third: 12x11x10
9 for the fourth
and 8 for the fifth
so your equation becomes: 12x11x10x9x8= 95,040 different groups of 5

Answer:
1/3
Step-by-step explanation:
Let A be the event that you grab the fair coin and B be the event that you toss a tail.
P(A) is the probability that you grab the fair coin, which is 1/3
P(B) is the probability that you toss a tail, which is 1/2
P(B|A) is the probability that you toss a tail, given that you grab a fair coin, which is 1/2
P(A|B) is the probability that you grab the fair coin, given that you toss a tail, which we are looking for.
Using Bayes probability theorem we have:
![P(A|B) = \frac{P(B|A)P(A)}{P(B)} = \frac{(1/2)*(1/3)}{1/2} = 1/3](https://tex.z-dn.net/?f=P%28A%7CB%29%20%3D%20%5Cfrac%7BP%28B%7CA%29P%28A%29%7D%7BP%28B%29%7D%20%3D%20%5Cfrac%7B%281%2F2%29%2A%281%2F3%29%7D%7B1%2F2%7D%20%3D%201%2F3)
