Question

which best describes independent events? the results of all events have different individual probabilities. the results of any previous events affects the probability of future events. the results of all events have the same individual probability. the results of all previous events do not affect the probability of future events.

Explanation:

• Independent events are defined such that the occurrence or non - occurrence of one event has no impact on the probability of another event.
• For the first option, having different individual probabilities is not the key characteristic of independent events.
• The second option describes dependent events (where previous events affect future probabilities), not independent ones.
• The third option about having the same individual probability is not the defining feature of independent events.
• The fourth option correctly states that the results of previous events do not affect the probability of future events, which is the essence of independent events.

Answer:

The results of all previous events do not affect the probability of future events.
