A disc jockey at a school dance has equal numbers of rock and pop songs
that she randomly selects from. She designs a simulation to estimate the
probability that the next three songs are all rock songs.
Which simulation design could she use to estimate the probability?
O
A. Number cube
Let 1 = rock
Let 2 = pop
Roll cube three times. Repeat.
O
B. Random digits
Let 0, 1, 2, 3 = rock
Let 4, 5, 6, 7, 8, 9 = pop
Select three random digits. Repeat.

C. Number cube
Let 1, 2, 3, 4 = rock
Let 5,6=pop
Roll cube three times . Repeat

D. Number cube
Let even number=rock
Let odd number =pop

step-by-step explanation:

i used the pitagoras theoreme

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
