The state lottery board is examining the machine that randomly picks the lottery numbers. On each trial, the machine outputs a ball with one of the digits 0 through 9 on it. (The ball is then replaced in the machine.) The lottery board tested the machine for 40 trials and got the following results. Outcome 0 1 2 3 4 5 6 7 8 9
Number of Trials 3 6 3 4 2 2 4 5 3 8

1. Assuming that the machine is fair, compute the theoretical probability of getting an 8 or 9?
2. From these results, compute experimental probability of getting 8 or 9?
3. Assuming that the machine is fair choose the statement below that is true:

a. with a small number of trails, it is suprising when the experimental probability is much less than the theoretical probability.
b. with a small number of trials, it is not suprising when the experimental probability is much less than the theoretical probability.
c. with a small number of trials, the experimental probability will always be much less than the theoretical probability.

Browning labs is testing a new growth inhibitor for a certain type of bacteria. the bacteria naturally grows exponentially each hour at a rate of 6.2%. the researchers know that the inhibitor will make the growth rate of the bacteria less than or equal to its natural growth rate. the sample currently contains 100 bacteria. the container holding the sample can hold only 300 bacteria, after which the sample will no longer grow. however, the researchers are increasing the size of the container at a constant rate allowing the container to hold 100 more bacteria each hour. they would like to determine the possible number of bacteria in the container over time. create a system of inequalities to model the situation above, and use it to determine how many of the solutions are viable.
