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

 2/5 and 3/10

Step-by-step explanation: Sample space S={0,1,2,3,4,5,6,7,8,9}

A:event of picking a odd prime number={1,3,5,7}

P(A)=4/10

      =2/5

B: event of picking a number greater 0 that is also a perfect square={1,4,9}

P(B)=3/10

45
