Question 471880: If the probability that an event will happen is expressed as 0.3, which of the following would be the best approximate for the odds in favor of that event happening? I just need to know if I have the correct answer of 3:1. If not, which on of the following choices would be the correct answer: A. .3:10 B. 7:10 C. 3:7. Thank you.

P(A)= 0.3 = 3/10
P'(A) = 1 - 3/10 = 7/10
ODDS IN FAVOR OF THIS EVENT = P(A)/ P'(A) = 3/7
ANS: C 3:7
