A bag contains tiles with the letters p -r-o-b-a-b-i-l-i-t-y Tyler chooses a tile without looking and doesn't replace it he chooses a second tile without looking what is the probability that he will choose the letter i both times

1/55
2/55
2/121
3/121

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:

1

step-by-step explanation:

it's the only multiple of both and the least

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
