During the summer, Olympic swimmer Adam Johnson swims every day. On sunny summer days, he goes to an outdoor pool, where he may swim for no charge. On rainy days, he must go to a domed pool. At the beginning of the summer, he has the option of purchasing a $$15$ season pass to the domed pool, which allows him use for the entire summer. If he doesnt buy the season pass, he must pay $$1$ each time he goes there. Past meteorological records indicate that there is a $60\%$ chance that the summer will be sunny $($in which case there is an average of $6$ rainy days during the summer$)$ and a $40\%$ chance the summer will be rainy $($an average of $30$ rainy days during the summer Draw the decsion tree
