You might want to look into beta regression, which deals with bounded dependent variables.

Removed R tag and added nonlinear regression tag. This really has nothing to do with R

comment How to check if people think 3 is a lucky number while we throw with 2 dice
Do you mean "Is the probability of picking both 1 and 3 independent of picking 1 and picking 3?" If picking 1 and picking 3 were independent then the probability would be 6/10 * 1/10 = 6/100. You got 5/100. You can test whether those two proportions are equal using, e.g. a t-test for proportions.

Then I don't understand what you are hypothesizing.
