Question 295629: A box contains ten balls, numbered 1 through 10. Marisha draws a ball. She records its number and then returns it to the bag. then Penney draws a ball. Find each probability.
1.P(9,then 3)
2.P( even,then odd)
3.P( odd,then 2)
4.P (the sum of the numbers is 25)
5.P(prime, the composite)
6.P(a factor of 8, then a multiple of 2)
Thank you for your time.

1.P(9,then 3) = (1/10)*(1/10)=1/100
2.P( even,then odd)=(1/2)*(1/2)=1/4
3.P( odd,then 2)=(1/2)*(1/10)=1/20
4.P (the sum of the numbers is 25)=0
5.P(prime, the composite)=((1/2)*(1/2)=1/4
6.P(a factor of 8, then a multiple of 2) =(1/10)*(1/2)=1/20
