Question 5: A civil engineer designing a bridge has specified several different diameter sizesto be used for structural bolting. Let Y= bolt diameter size (measured in inches) where Y has thefollowing the distribution:%3|137y1248.p(y)0.110.230.370.29a) What is the average diameter size used in the bridge design?b) Suppose 6 bolt locations in the design are randomly sampled and the bolt diameter size isrecorded. Let Xbe the number of 1-inch bolt diameters in the sample. Find P(X=2).

The average diameter size is defined as E(Y) = Σy. P(y) Where Y denotes the bolt diameter size.
