$40$ weeks or less is

$0\mathrm{.}227$

$0\mathrm{.}227.($Enter as a probability and round your response to three decimal$$ places.$)$

I DON$$T UNDERSTAND HOW TO FIND THE probability from the chart. How do obtain the $0\mathrm{.}227$

z$=$x$-$u$/$o

square root of $12\mathrm{.}84=3\mathrm{.}58$

$=40-42\mathrm{.}67/3\mathrm{.}58=-0\mathrm{.}7458100559$

How do I get the O$\mathrm{.}227$ from $-0\mathrm{.}746$ looking at standard normal table
