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?

AUB = {E1, E2, E4, E6, E7}

Step-by-step explanation:

Since we are to look for the union of the two sets, therefore we combine all the sample points that are contained in A and B without repeating any sample even if such sample occur in both sets. For example, E4 occurs in event A and B and as such will only be repeated once in the union of the two events.

AUB = {E1, E2, E4, E6, E7}

Note that the way you arrange does not matter as well.

I hope you find this solution useful?

hi,

you half the rectangle that you ae asking about so then you would see the scale factor of 1/2 the one u have selected, the one on top is half.

hope this !
