(1 point) The length of an insect (L, in mm) is a function of the temperature during development (T , measured in ∘C according to L(T)=8+T10 ) . The volume of the insect (V , in cubic mm) is a function of the length according to V(L)=7L3 . The mass (M in milligrams) depends on volume according to M(V)=1.1V . Find mass as a function of temperature. M(T)= How much would an insect weigh that developed at 22∘C?

The symbol ∪ represents the union of events. The union of two events A and B results in an event that contains all the sample points of event A or event B or both events. Therefore, A ∪ B is a new event that lists the sample points of event A or event B or both events. Recall the set notation used for an event with k sample points. event = {sample point 1, sample point 2, , sample point k} Event A is made up of the sample points E1, E4, and E6 and event B is made up of the sample points E2, E4, and E7. Thus, the union of events A and B will have what sample points that are contained in either A or B?
