A dice is rolled 50 times. It lands on six 37 times. Compare the theoretical and experimental probabilities of rolling the dice and describe any discrepancies.

The theoretical probability is 74% and the experimental probability is 17%. The difference is 57%, therefore they are not close. Not enough trials were done.

Jessica wants to test if a coin is biased. She throws the coin 24 times. The results are shown below. Compare the theoretical and experimental probability of getting heads and describe any discrepancies.

The theoretical probability of getting heads is 50% and the experimental probability of getting heads is 54%. They are not close. They did not perform enough trials.

Ayra can either walk away with $100 or play a game where she must roll a six-sided dice for a chance to win more. If Ayra rolls a 6, she wins $200, but if she rolls anything other than a 6, she walks away with nothing. Should she roll the dice based on how likely, or unlikely, it is to roll a 6?

She should roll the dice because she is likely to roll a 6.

She should not roll the dice because she is likely to roll a 6.

She should roll the dice because she is unlikely to roll a 6.

She should not roll the dice because she is unlikely to roll a 6.

You are on a game show that has 5 doors that have items hidden behind them. The host offers you $200 guaranteed if you walk away and don't play the game. Two of the doors have $20 behind them, two different doors have $250 behind them, and one door has $500 dollars behind it. Should you play the game based on how likely, or unlikely, you are to win equal or more money than just walking away without playing the game?

You should not play the game because you are more likely to win $200 or more.

You should not play the game because you are unlikely to win $200 or more

You should play the game because you are more likely to win $200 or more

You should play the game because you are unlikely to win $200 or more.
