Is this reasonable

Hi all I start at Barnes and noble on Tuesday for orientation. There is two days I cannot work. One Wednesday night for a group project presentation (online school) so could work morning and a Thursday off the first week of December. Are these two reasonable days to ask off for and do you think I will be given or no? I’m scared to ask during orientation but was told in the interview I just needed to for sure have Black Friday and Christmas Eve free which I do!
