X= # of people who attended the movie

Numerator= # of people under 30
Denominator= total # of people

60/100 = 1200/x
Then we cross multiply
60x = 120000
x = 2,000

Final answer= 2,000 people attended the theater

Nine tiles numbered 1 through 9 are placed in a bag. A tile is randomly drawn and replaced. Then a

Answer:

16/81

Step-by-step explanation:

As the tile is taken and then replaced this means that the probability of the second event is not impacted by the probability of the first (they are independent)

As there are 9 tiles and 4 of them are even, the probability that the first tile drawn is even is 4/9.

There are still 9 tiles and still 4 of them are even for the second tile being drawn so this probability is then also 4/9.

If we want to find the probability of both events we should multiply together these two independent probabilities.

So: $\frac{4}{9} *\frac{4}{9} =\frac{16}{81}$
