Which of the following are true for probability? CHECK ALL THAT APPLY!
| a) |
If P(A)=0 for an event A, that means A cannot happen. |
|
| b) |
The total probability of all possible outcomes of an experiment adds up to 1. |
|
| c) |
P(A|B) = P(A) means that these two events are independent. |
|
| d) |
The probability is a value between -1 and 1. |

30 students enter classroom 319 through two doors. Assume that the probability of entering through the left door is the same as the probability of entering through the right door and is 1/2. What is the probability of the event that 30% of the students enter through the left door and 70% of the students enter through the right door?

CNAE, an all-news AM station, finds that the distribution of the lengths of time listeners are tuned to the station follows the normal distribution. The mean of the distribution is 12.6 minutes and the standard deviation is 4.1 minutes. Refer to the table in Appendix B.1. What is the probability that a particular listener will tune in: (Round the intermediate calculations to 2 decimal places and the final answers to 4 decimal places.)
a. More than 20 minutes?
Probability
b. For 20 minutes or less?
Probability
c. Between 10 and 12 minutes?
