Setting Up Probability for Casting Concrete: E1, E2, and E3 Events Defined

[HeheZz]

This is my question:

E1 = there is no rain
E2 = concrete material production is feasible
E3 = premix concrete is available

On a day given, casting concrete depend on the availability of material. The required material may be produced and send to the site from premix concrete supplier. However, it is not certain the premix concrete will always be available. Furthermore, whenever when its raining, casting cannot be perform.
The following events were defined: P(E1) = 0.8, P(E2)=0.7, P(E3|E2')=0.6

Identify the following events in terms of E1, E2, E3.
A = Casting concrete elements can be performed on a day
B = Casting concrete elements cannot be performed on a day

E2 and E3 are statistically independent of E1
