$$ \displaylines{\\ \\ x = 22 \\ \\ \mu = 24.0 \\ \\ \sigma = 2 \\ \\ n = 3 \\\;\\\;Formula\;for\;z\;is \\ \\ Z= \frac{x - \mu }{\frac{\sigma }{\sqrt{n}}} \\ \\ So, Z = \frac{22-24.0}{\frac{2}{\sqrt{3}}} \\ \\ \Rightarrow \frac{-2.0}{1.154701} \\ \\ \Rightarrow -1.73205 \\ \\ As\;per\;question\;we\;need\;to\;find\;probability\;of\;X<22.\\\;\\\;That\;is\;Z<-1.73205 \\ \\ P(Z<-1.73205) = \mathbf{\color{Red}{0.041632}} \left [ From\;z\;table \right ] \\ \\ Therefore\;probability\;of\;x\;less\;than\;22\;is\;\;\mathbf{\color{Red}{0.041632}} } $$
