Answer:
Step-by-step explanation:
Total number of tiles: 11 (obtained from counting the letters in probability)
Probability of picking the letter "i" the first time:
There are 2 letter "i's", and 11 total options, so the probability of picking an "i" is:
Probability of picking the letter "i" the second time:
We now have one less letter in the bag, as the first letter "i" was not replaced.
This means we now only have 1 letter "i", and 10 total options, so the probability of picking the last "i" is:
When you have two probabilities that are dependant on each other, you multiply them to get the probability of one, given that the other has happened.
Total probability:
Simplify by dividing by 2:
