Question

Blocks numbered 0 through 9 are placed in a box, and a block is randomly picked.

The probability of picking an odd prime number is . The probability of picking a number greater than 0 that is also a perfect square is .

Answer 1

1. the probability of picking an odd prime number is 1/5.
2. the probability of picking a number greater than 0 that is also a perfect square is 3/10.

Step-by-step explanation:

QUESTION 1:

There are two odd prime numbers between 0 and 9: 3 and 7. Since there are a total of 10 numbers (0 through 9), the probability of picking an odd prime number can be calculated as:

Probability = (Number of Odd Prime Numbers) / (Total Number of Numbers)

Probability = 2 / 10

Probability = 1/5

QUESTION 2:

Perfect squares between 0 and 9 are 0, 1, 4, and 9. Since we want a number greater than 0, we can exclude 0 from the list. So, there are three perfect square numbers greater than 0: 1, 4, and 9.

The probability of picking a number greater than 0 that is also a perfect square can be calculated as:

Probability = (Number of Perfect Square Numbers) / (Total Number of Numbers)

Probability = 3 / 10

Probability = 3/10
