Normal probability model

You want to go to Mt Hotham for snowboarding sometime in the JulyAugust season (defined as the days inclusive of July-August only), as you can see that the peak in "days with significant snowfall" occurs across these 2 months. The number of 'predominant snowfall' days (defined when snowfall is 5 cm) in the days of July-August varies according to a Normal distribution with a mean of 30 days of snowfall across that particular period and standard deviation of 5 days. Include a shaded in density curve to each answer.
