Find the probability that the number of boxes delivered will be atleast 37 but not more than 50

Answer 1

$$\def\arraystretch{1.5} \begin{array}{c:c} Day & Number\ of\\ & boxes \ (X)\\ \hline 1 & 35 \\ \hdashline 2 & 37 \\ \hdashline 3 & 50 \\ \hdashline 4 & 45 \\ \hdashline 5 & 37 \\ \hdashline 6 & 45 \\ \hdashline 7 & 40 \\ \hdashline 8 & 42 \\ \hdashline 9 & 45 \\ \hdashline 10 & 42 \\ \hdashline \end{array}$$

$$P(37\leq X\leq 50)=\dfrac{9}{10}=0.9$$
