The odds that a certain event will occur is the ratio of the probability that the event will occur to the probability that it will not occur. If the odds that Pat will win a prize are 4 to 3, what is the probability that Pat will not win the prize ?
(A)1/4
(B)1/3
(C)3/7
(D)4/7
(E)3/4
Read Solution (Total 10)
-
- Total number of chances=4+3=7
P(winning the prize)=4/7
P(not winning the prize)=1-(4/7)=3/7
(...As P(winnig)+P(nt winnig)=1) - 10 years agoHelpfull: Yes(42) No(1)
- 3/7,,,,,,very simple
- 10 years agoHelpfull: Yes(6) No(9)
- ans is 3/7
- 10 years agoHelpfull: Yes(5) No(4)
- probability that the event will occur/will not occur
probability that the event will occur(P) is 4/7
==>P/(1-P)=4/3
==>P=4/7 --> 1-P = 3/7(ans) - 10 years agoHelpfull: Yes(5) No(0)
- P/(1-P)=4/3
P=4/7
1-P = 3/7 - 10 years agoHelpfull: Yes(5) No(0)
- odd=p(occur)/p(not occur)=win/not win=4/3=(4/7)/(3/7)
=> p(not win)=3/7 - 10 years agoHelpfull: Yes(3) No(0)
- p(f/u) = 4/3,
p(u/t)= 3/7 Ans. - 10 years agoHelpfull: Yes(1) No(0)
- ans is 3/(3+4)
- 10 years agoHelpfull: Yes(0) No(1)
- 3/7 is the answer
- 10 years agoHelpfull: Yes(0) No(1)
- 3/7 3= loose 4=win
loose /total - 9 years agoHelpfull: Yes(0) No(0)
