Answer:

a. I would put 20 stuffed animals in the bin, out of which 10 would be teddy bears.

So that the probability is 10/20 = 1/2

b. I could remove 8 other animals from 12 to have 4. So that the total number of stuffed animals is 8. 4/8 = 1/2

Step-by-step explanation:

a. Probability =

number of required outcomes / number of possible outcomes

If in the bin there are 10 teddy bears out of 20 stuffed animals,

Then the probability of picking a teddy bear = 10/20 = 1/2.

b. If on returning, there are 4 teddy bears and 12 other animals, I could simply remove 8 of the other animals to have 4 other animals and a total of 8 stuffed animals.

Probability = 4/8 = 1/2
