PROBABILITY MATH

posted by on .

From a group of 3 men and 4 women, a delegation of 2 is selected at random. What is the expected number of men in the delegation? Round your answers to two decimal places as needed.

Could someone help me with how to do this?

  • PROBABILITY MATH - ,

    0: p(0) ((3C0)(4C2)/7C2)
    1: p(1) ((3C1)(4C1)/7C2))
    2: p(2) ((3C2)(4C0)/7C2))

    Now to find expected number, multiply the p by the probability. Good luck!
