What do you mean about that
A = p(1 + rt)
A/p = 1 + rt
rt = A/p - 1
t = (A/p - 1)/r
So the probability is the number of favorable outcomes divided by the number of total outcomes. This means that the favorable outcomes are 7/9, and the unfavorable outcomes are 2/9. The odds against the event are the unfavorable outcomes. Therefore the odds against the event is 2/9, or 0.2 repeating. Hope this helps.
