Answer 1

The probability of picking an odd prime number is 3/10
The probability of picking a number greater than 0 that is also a perfect square is 3/10

I'm pretty sure thats right...

Answer 2

Answer with explanation:

We have been given that blocks numbered 0 through 9 are placed in a box and a block is randomly picked.

Total numbers = 10

Now we will count the numbers in each category.

Prime numbers: 4 (2,3,5,7)

Odd numbers in prime : 3 (2,5,7)

Perfect square : 3 (1,4,9)

Greater than 0 and perfect square : 3 (1,4,9)

Now, the probability of picking an odd prime number is : Odd prime numbers are '3' and total are '10' , thus probability is : $\frac{3}{10}$

The probability of picking a number greater than 0 that is also a perfect square is also $\frac{3}{10}$. (there are '3' perfect squares greater than 0)
