Answer 2

It's the same question but now it's a 3:1200 probability, pay attention to those keywords. What is the probability that Sophie, Hannah OR Ethan will win the bike? That OR tells us that we can combine them as 1 statistic, hence 3:1200.
So now we have {SS, HS, ES, NS} where SS = Sophie Selected, HS = Hannah Selected, ES = Ethan Selected and NS = None Selected.

Answer 3

im a little confused lol

Answer 4

Okay, well here's what you do. Take the answers to the last question we did, the one where JUST sophie was gonna win the bike when we did 1:1200. Take that question and just change the values from 1:1200 to 3:1200 since there are 3 people we want to win the bike.

Answer 5
