Area and Volume
Two athletes A and B participate in a race along with other athletes. If the chance of A wining the race is 1/6 and that of B wining the same race is 1/8, then the chance that neither wins the race is
Read Solution (Total 3)
-
- Sample space of the above =
{ A win others lose, B win others lose, Others win A&B lose}
P(A win)+P(B win) + P(others win)=1
1/6 + 1/8 +P(A&B lose)=1
P(A&B lose)= 17/21 - 8 years agoHelpfull: Yes(5) No(1)
- p(a)=1/6
p(b)=1/8
p(a)+p(b)+p(other)=1
P(other)=1-1/6-1/8=17/24 - 8 years agoHelpfull: Yes(2) No(3)
- 1 - {(1/6)(7/8) + (5/6)(1/8) - (1/6)(1/8)}
= 37/48 - 8 years agoHelpfull: Yes(0) No(0)
