Answer:

1/25

Step-by-step explanation:

At the start there is a 4/20 (1/5) chance of drawing a blue marble. After putting the marble back in the bag, there is again a 1/5 chance of drawing a blue marble again. To calculate the overall probability, you must multiply the two numbers together: 1/5 x 1/5 = 1/25.

All the fraction that are greater than 1\2

Hi There!

Change all the fractions to decimal you do that by dividing numerator by the denominator. Remember \frac{1}{2}   as a decimal is 0.5

A=  \frac{3}{7}  =    0.43

B=  \frac{5}{9}  =    0.60

C=  \frac{8}{10} =   0.8

D=   \frac{5}{12} =   0.42

E=    \frac{3}{5}   =   0.6

Based, on the data above B,C,E are greater than \frac{1}{2} because they all have decimals greater than 0.5, B= 0.6, C= 0.8, E=0.6

So, \frac{5}{9} ,\frac{8}{10} ,\frac{3}{5}  are all greater than \frac{1}{2}

Hope This Helps :)
