Answer 1

8 Total Line 2 147 82 65 8 Good Defective total 13 N = 160 (line 2) = 90 n (line 1) = 70 probability that this part is made from Line I n(line 1) 160 Answer 10.44 Ivote for Democratic vote for Republic Tortal party party (A) male (6) INCANB)- 280 n(B) =520 240 Female 1go 490 ago Total n(A)= 470 jooo A: The event that selected person will vote for Republic party B. The event that selected person is a male P(AUB) = P(A) + P(8) n(A) + n (B PLANB) CANB) N = 470 + 520 280 1000 = 4 tot 520 +280 1000 = 710 looo P(AUB) = 0.71 Answer To.FI
