I looked at the rest of the multiple choices had >.5 probabiliy of putting 2 ladies forward as executives when they are already the minority. Hence it seems logical to pick C. |

4/10*3/9 |

Pardon my ignorance, but where is the 3/9 coming from? |

probability of first female = 4/10 now there is one less female and one less person overall to select therefore probability of second female is 3/9 |

Yeah, I didn't make the 3/9 intuition, but there is no way A and B could be accurate so I went with C. |

I just knew it couldn't be the other two. Glad to know the affirmative action info is just meant to distract |
