If two orders are selected, find the probability that they are both from Restaurant D.

a. Assume that the selections are made with replacement. Are the events independent?

b. Assume that the selections are made without replacement. Are the events independent?

a. Assume that the selections are made with replacement. Are the events independent?

The probability of getting two orders from Restaurant D is ______. The events ______are are not independent because choosing the first order ______does not affect affects the choice of the second order. (Round to four decimal places as needed.)

The probability of getting two orders from Restaurant D is ___ The events____ independent because choosing the first order

____the choice of the second order.

Answer #1

Ans:

accurate | not accurate | Total | |

A | 323 | 36 | 359 |

B | 279 | 52 | 331 |

C | 234 | 38 | 272 |

D | 126 | 14 | 140 |

Total | 962 | 140 | 1102 |

a)P(both are from D)=(140/1102)*(140/1102)=0.0161

The probability of getting two orders from Restaurant D is
**0.0161.** The events **are
independen**t because choosing the first order **does
not affect** the choice of the second order.

b)

P(both are from D)=(140/1102)*(139/1101)=0.0160

The probability of getting two orders from Restaurant D is
**0.0160.** The events **are not
independen**t because choosing the first order
**affects** the choice of the second order.
