A reporter covering a naturalization ceremony wants to randomly select new citizens to interview. Out of the 200 new American citizens, 7 of them are from Ecuador, and 10 of them are from Kenya. What is the probability that the reporter will randomly select a person from Ecuador first and then a person from Kenya to interview?

  • Probability, not "9th grade" - ,

    Please type your subject in the School Subject box. Any other words are likely to delay responses from a teacher who knows that subject well.

    7/200 for the Ecuadorian, 10/199 for the Kenyan (one non-Kenyan person is already gone).

    The probability of both (or all) events is found by multiplying the probabilities of the individual events.

    I hope this helps.

    The answer is 7/3,980. By the way, this is 6th grade, not 9th!
