Answer:
4:7
Step-by-step explanation:
Given is a word Mississippi
We have number of s's in this word is = 4
Total words = 11
An odds ratio (OR) is generally a measure of association between an exposure and an outcome. Thus we see that the OR represents the odds that an outcome will occur given a particular exposure, compared to the odds of the outcome occurring in the absence of that exposure.
It can be calculated as ratio of favourable outcomes:unfavourable outcomes
Hence in this question favourable outcomes =4
unfavourable = 11-4 =7
SO odds ratio = 4:7
