Determine the probability of selecting two fakes
The probability can be represented as thus: 
Using the following probability formula, we have:
Each probability is calculated by dividing number of fakes by total number of gems:
The minus 1 (-1) represent the numbers of fake and total gems left after the first selection
<em>Hence, the required probability is approximately 0.504</em>
Answer:
- 3/4
Step-by-step explanation:
-2 1/2 - (-1 3/4)
Subtracting a negative is like adding
-2 1/2 + (1 3/4)
Get a common denominator of 4
-2 2/4 + 1 3/4
The signs are different so we subtract and take the sign of the larger
2 2/4 - 1 3/4
Borrowing from the 2
1 4/4 + 2/4 - 1 3/4
1 6/4 - 1 3/4
3/4
2 2/4 was larger and it was negative so we add a negative sign
- 3/4
