Probability Question?

The weight of flour, in grams, found in a standard cup of flour is a uniformly distributed random variable that ranges from 122.17 to 118.67 grams. A pastry recipe from a European cookbook calls for 120 grams of flour. If a baker uses 1 cup instead, what is the probability that there will be more flour in the dough than is called for in the recipe? Give your answer to four decimal places.
