Best ResponseYou've already chosen the best response.0(so 3/6 possibilities for the second die to make an odd number) = 50%

Best ResponseYou've already chosen the best response.0that's generally how these work  you want to consider <success case>/<total possibilities>  especially given all possibilities are equally likely e.g. a fair die
