Question #233687
The probability of randomly selecting a student with a height of exactly 154 cm.
Expert's answer
The heights of 1000 students are approximately normally distributed with a mean of 154.5cm and a standard deviation of 3.0cm.
The probability of randomly selecting a student with a height of exactly 154 cm.
Because there is an uncountable infinite number of a value of X, therefore the probability of each individual value is zero.
P(X=154) =0
