13,571 PointsChallenge Task 2 of 2 In the ParseWeatherForecast method, use double.TryParse to parse the PrecipitationChance and PrecipitationAmount properties from the value of values[4] and values[5] respectively, and add the parsed values to the weatherForecast object. Don't forget to declare the variable to hold the out parameter to pass to the TryParse method.
