P+Q=1
Q=1-P
C>=73
C=65P+85Q
73=65P+85(1-P)
73=65P+85-85P
73-85=-20P
-12=-20P
P=12/20 =0.6
74=65P+85(1-P)
74=65P+85-85P
74-85=-20P
-11=-20P
P=11/20 =0.55
P will be less than 0.8
Ans B
Q=1-P
C>=73
C=65P+85Q
73=65P+85(1-P)
73=65P+85-85P
73-85=-20P
-12=-20P
P=12/20 =0.6
74=65P+85(1-P)
74=65P+85-85P
74-85=-20P
-11=-20P
P=11/20 =0.55
P will be less than 0.8
Ans B
