Question

I have a question, which I cannot find the correct solution to from my book.

- Your school Ping-Pong team is not performing very well this
season. After some rough calculations, you found out that your
team's probability of winning a game is about 0.45. A fellow team
member want to know more and asked you also to determine the
following.

a) The probability of the team winning 2 games out of 5

b) The probability of winning 10 times out of 25

Thank you so much in advance! I have answered the question
myself, but would like to compare to someone else's answer to be
sure that I am thinking correctly.

All the best,

Naomi

Answer #1

p = 0.45, q = 1 - p = 0.55

The binomial probability formula is P(x) = C(n, x) p^x q^(n - x)

(a) n = 5, x = 2

x |
P(x) = C(5, x) 0.45^x 0.55^(5 - x) |

0 | 0.0503 |

1 | 0.2059 |

2 | 0.3369 |

3 | 0.2757 |

4 | 0.1128 |

5 | 0.0185 |

P(2) = 0.3369

(b) n = 25, x = 10

x |
P(x) = C(25, x) 0.45^x 0.55^(25 - x) |

2 | 0.0001 |

3 | 0.0004 |

4 | 0.0018 |

5 | 0.0063 |

6 | 0.0172 |

7 | 0.0381 |

8 | 0.0701 |

9 | 0.1084 |

10 | 0.1419 |

11 | 0.1583 |

12 | 0.1511 |

13 | 0.1236 |

14 | 0.0867 |

15 | 0.0520 |

16 | 0.0266 |

17 | 0.0115 |

18 | 0.0042 |

19 | 0.0013 |

20 | 0.0003 |

21 | 0.0001 |

22 | 0.0000 |

23 | 0.0000 |

24 | 0.0000 |

25 | 0.0000 |

P(10) = 0.1419
