Question

A table is shown below that shows some of the individual and/or cumulative probabilities for a discrete random variable which has a possible values at all integers from 0-20.

a) fill in the missing values that you can find for the table from the given information.

FInd the probability that X is ...

b) ...at most 18

c) ...less than

d) ...less than

f) ...more than 4

g) ...between 4 and 16, inclusive

possible values | individual probabilities | cumulative probabilities |

x | P (X = x) | P (X <_ x) |

0 | .032 | |

1 | .051 | |

2 | .100 | |

3 | .044 | |

4 | .186 | |

5 | .034 | |
