Question

Question 18 (1 point) suppose that we have a sample space S = {EpE2' Eg' E4: Es E6, E7}, where E1, E2, , E, d sample points (outcomes). The following probability assignments apply: P(E)-0.1, p(E2) = 0.2, p(E3) = 0.15, p(E4) 0.2, p(Es)-0.11P(Eg) = 0.05, and P(Ey) = 0.2. Assume the following events when answering the questions. A = (Ei, E4, E6) B = (E2, E4, E7) c = (E2, E3, E5, E7) What is P (A U B)? Answer to two decimal places. Your Answer: Answer Save Question 19 (1 point) E7 denote the suppose that we have a sample space s = {E1, E2, E3, E4, Es-E6, E7}, where E1, E2, sample points (outcomes). The following probability assignments apply:

Explanation / Answer

Question 18

Answer :

Let A ={E1, E4, E6}

B={E2, E4, E7}

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

P(AUB) =P(E1) +P(E2) +P(E4) +P(E6) +P(E7)

P(AUB) =0.1+0.2+0.2+0.05+0.2

P(AUB)=0.75
