Find to 4 decimal places the probability that x assumes a valuea. between 27 and 33.Probability = Enter you answer in accordance to the item a) of the question statement b. between 19 and 35.Probability = Enter you answer in accordance to the item b) of the question statement

Answer 1

`\begin{gathered} \mu=23 \\ \sigma=6 \end{gathered}`

a.
