Question

A group consisting of 6 people is to be selected from eight parents and four teachers.

Answer 1

Answer:

9/32 or 0.28125

Step-by-step explanation:

8 parents and 4 teachers

There are 12 possible outcomes.

probability = # of favorable outcomes / # of possible outcomes

Let's do the teachers first.

There are 4 teachers, and we are finding the probability for 3 of them being picked.

Therefore,

P = 3/4

Now let's do the parents.

There are 8 parents, and we want 3.

Therefore,

P = 3/8

Now, we do  $\frac{3}{4} *\frac{3}{8} = \frac{9}{32}$

Therefore, the chance of 3 teachers and 3 parents being picked out of 4 teachers and 8 parents is 9/32, or in decimal form 0.28125.

Hope this helped!
