Question

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

we know that

total blocks=10

total odd prime numbers------> 3,5,7------> 3 numbers

so

Part 1

The probability of picking an odd prime number is

P=3/10 or P=0.3

Part 2

total blocks=10

total numbers greater than zero also a perfect square ------>1,4,9---> 3 numbers

so

The probability is

P=3/10 or P=0.3
