1.theoretical is not counting the results of the experimentssince there are an equal number of red and black and red, the probblity (theoretical) of picking a black one is 1/3 experimental=number of outcomes happened/total number of tests4 times black, 4 tests, so 4/4 or 100%=experimental proablity
2. experimental considered previous trials and theoretical did not
3. theoretical=(1/4) the trials don't influence each other so1/(4*4)=1/16
