Read Solution (Total 7)
-
- employees play hockey= 200-125= 75
employees play cricket = 100
play both= 50
then P(AUB) = P(A)+P(B)-P(A intersection B) = 100+75-50 = 125 - 10 years agoHelpfull: Yes(30) No(1)
- CuH=100+(200-125)-50=125
- 10 years agoHelpfull: Yes(2) No(0)
- P(K)+P(H)-P(K&H)=P(K U H)=125
- 10 years agoHelpfull: Yes(1) No(0)
- cricket:C=100
hockey:H=200-125=75
C and h both=50
atleast one game=CUH=100+75-50=125 - 7 years agoHelpfull: Yes(1) No(0)
- p(aUb)=p(a)+p(b)-p(a intersection b)
=100+(200-125)-50
125 - 10 years agoHelpfull: Yes(0) No(0)
- employees play hockey=200-125=75
so,P(CUH)=P(C)+P(H)+P(CnH)=100+75-50=125 - 10 years agoHelpfull: Yes(0) No(0)
- consider A=100(employee play cricket) B=200-125(employee play hockey)=75 given A∩B=50
therefore A∪B=A + B - A∩B=100 + 75 - 50 = 125 - 8 years agoHelpfull: Yes(0) No(0)
