The table shows the probabilities of winning or losing when the team is playing away or is playing at home.
Home away Total
Win 0.2 0.05 0.25
Loss 0.6 0.1 0.7
Total 0.8 0.15 1.00
(a) Are the events “winning” and “playing at home” independent? Explain why or why not.
(b) Are the events “losing” and “playing away” independent? Explain why or why not.

Although the experimental probability shows that playing at home gives a certain edge, mathematically the events "winning" and playing at home are completely independent since the 2 events are not linked whatsoever.
Just take the example of flipping a dye. The probability of getting a Head = 1/2.
If after 1000 flips you get a head, the probability of getting a Head on the 1001 flips is always 1/2 (head & tail are independent)

Same reasoning for the 2nd question

Answer:

A)The events "winning" and "playing at home" is independent.

b) The events "lossing" and "playing away" is independent.

Step-by-step explanation:

Independent Events: Two events are dependent if the result of the second event depends on the result of the first events.

Dependent Events: Two events are independent if the result of the second event is not affected by the result of the first event.

a) The events "winning" and "playing at home" is independent because the result of the second event depends on the result of the first events.

b) The events "lossing" and "playing away" is independent because the result of the second event depends on the result of the first events.
