A jewelry store has 20 pins for sale and 38 other pieces of jewelry.
What is the probability that a randomly selected piece of jewelry will be a pin?
Simplify your answer and write it as a fraction or whole number.
there are 58 total pieces (20 + 38) ... what fraction are pins?
To find the probability of randomly selecting a pin from the jewelry store, we need to know the total number of pieces of jewelry in the store and the number of pins available.
Here, the total number of pieces of jewelry is given by the sum of pins and other pieces of jewelry: 20 pins + 38 other pieces of jewelry = 58 total pieces of jewelry.
The probability of selecting a pin can be calculated by dividing the number of pins by the total number of pieces of jewelry: probability = number of pins / total number of pieces of jewelry.
So, the probability can be calculated as follows:
probability = 20 pins / 58 total pieces of jewelry
To simplify the answer, we can divide both the numerator and denominator by their greatest common divisor, which is 2 in this case.
probability = (20 / 2 pins) / (58 / 2 total pieces of jewelry)
probability = 10 pins / 29 total pieces of jewelry
Therefore, the probability of randomly selecting a pin from the jewelry store is 10/29.
