Unformatted text preview: us random variables v༇  If Y is a continuous random variable, P(a <Y<b) is the area under the density curve above the interval between a and b v༇  Note: All continuous probability distributions assign probability zero to every individual outcome: P(Y=y) = 0 Recall & compare with discrete case: p( y ) = P (Y = y ) ≠ 0 ∑ p( y ) = 1 Continuous R.V: Mean and Median v༇ A mode of a density curve is a peak point of the curve. v༇ The median of a density curve is the point that divides the area under the curve in half. v༇ The mean of a density curve is the point at which the curve would balance if made of solid uniform material. Example: Continuous R.V. Eg. X is the location of the pointer of a spinner Normal Densities v༇  Bell- shaped, completely speciZie...
