Answer:
Similar
Step-by-step explanation:
There are two triangles in this picture, ABC and A'B'C'. Triangle ABC have 2 base and 2 height. Triangle A'B'C' have 6 base and 6 height, which is 3 times larger than ABC. When two objects have the same shape but different size, it is called similar.
A similar object can be made by using dilation transformation. In this case, ABC triangle have been dilated by 3 times to make A'B'C'
Theoretical: desired outcomes/total possible outcomes
the same as it was his first time picking before since the prevous results have no bearing on what this trial will yeild
if he didn't replace the marbles then it would be differnt
experimintal=number of event occurnces/total number of trials
so 4/4 or 100% is experimental
so
equal number of red and black and white
1/3 of the bag is black
therefor the probablity of picking a black marble is 1/3
A. 1/3 is theoretical, 4/4=experimental
B. differnce? dunno sorry
C. 4 in a row
1/3*1/3*1/3*1/3=1/81
