Biryani is one of the most loved meals served in Kadamba mess. Let the amount of rice served is normally distributed with mean of 370g and standard deviation of 24g. The amount of curry served is also a normal distribution of 170g and a standard deviation of 7g. Assuming the amount of rice and curry served is independent of each other, Find the prob- ability that the weight of the plate (consists of rice and curry only) is less than 575g.
