Is it symmetric, positively skewed or negatively skewed distribution?

In terms of the median, mode, and mean of the question, I got the correct answer of the mean being 2.7, mode 2.5, and median 2.5, which I had plotted in the above histogram. My concern was that apparently this is a symmetric distribution (uniform) and I didn't understand why because the mean, media, and mode are not all equal, other than the mode and the median. So wouldn't this be negatively skewed distribution? I'm not sure at all, please explain.

don't forget the mode is also 2.5, so how can it be positively skewed if not just the mode is also the lowest but also median. It says it's uniform distribution and I just don't understand why, is it because the 2.7 is close to 2.5 so it is considered as uniform?

Look up the definitions, read them as Raymond said above; the comparisons needed are between the mean and the median. You can also check out some images on the internet as well.

I know the definitions! They clearly don't match and also his answer is incorrect?
