- Determine whether the distribution is a discrete probability distribution

X | P(X) |

0 | 0.16 |

1 | 0.21 |

2 | 0.26 |

3 | 0.21 |

4 | 0.16 |

Is the distribution is discrete probabilty distribution? Why?

CHOOSE CORRECT ANSWER.

- No because some of the probability have value greater than 1 less than 0
- Yes because the probability sum to 1 and are all between 0 and 1, inclusive.
- Yes because the distribution is symetric
- No because the total probabilty is not equal to 1.

- A frequently distribution below. Complete A through E

- Use the frequently distribution to construct a probability distribution.

X | P(X) |

0 | ? |

1 | ? |

2 | ? |

3 | ? |

4 | ? |

5 | ? |

- Find the mean of the probabilty distribution
Means= ….. (round nearest tenth as needed )

- Find the variable of probabilty distribution
02=

- Determine which of the following could not represent the probability of an event.
A= 0

B= 0.009

C= 550/1259

E= 50%

F= -0.7

- You randomly selected one card from a standard desk.
Event A is selecting a five. Determine the # of outcomes in event A. Then decide whether the event is a simple or not?

The number of outcomes in the event is ?

IS event A simple Event?

Yes or No?

- Use the bar graph below, which shows the highest level of education received by employees of a company, to find the probability that the highest level of education for an employee a Random is B.
__Must insert Data

A =8

B= 26

C= 33

D= 17

E= 7

F= 13

The probability that the highest level of education for an employee chosen at random is B is?

- Determine whether the Events E & F are Dependent
Justify your answer.

- E: A person having a high GPA
F: A person being highly organized

Chose the correct one:

- E & F: are dependent because having a high GPA has no effect on the probability of a person being highly organized.
- E & f: are independent because highly organized has no effec on the probability of a person having a high GPA
