Hi, I am stuck on this problem and I am not sure how to begin it.

In an experimental study, researchers had each of their participants bet on each game of a professional football season. In the contingency table below is some information from a random sample of 100 bets from this study placed on the Columbus Crush (picking them to win) during the last 14 games of the season (the Crush had 7 wins and 7 losses over that period). The table indicates, for each bet placed on the Crush, whether or not the team won and how the participant who placed the bet wagered the following week. Each bet is classified according to two variables: result ofplcklng the Crush ("Crush won" or "Crush lost") and bet placed the following week ("Picked Crush to win" or "Picked Crush to lose"). In the cells of the table are the respective observed frequencies, and three of the cells also have blanks. Fill in these blanks with the frequencies expected if the two variables, result ofpicklng the Crush and bet placed the following week, are independent. Round your answers to two or more decimal places. Send data to Excel Result of picking the Crush Picked Crush to win Bet placed the following week Picked Crush to lose 21 54 Crush lost
