Hi there,I need some help with my stats homework. I am really struggyling with stats and need some advice on how to improve.There are 15 students, 15 chairs, 4 wear glasses, 7 wear hoodies.How many ways can you sit on these chairs: 1. so that Richard and David do not move2. so that Robert and Hannah stay sitting next to each other3. so that the students wearing glasses sit next to each other 4. so that Joe and Megan are sitting 'at the ends'5. so that the students wearing hoodies do not sit next to each other and those without do not sit next to each other 6. so that James does not sit next to Ben.*Apparently the hardest question. so that the students wearing glasses do not sit next to each other.
Are you going to achieve yours?
