Answer 2

4:7

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
