Questions and Answers

What is the probability of an event, according to the text?

  • The probability of an event is a random number between 0 and 1.
  • The number of favorable outcomes divided by the total number of outcomes. (correct)
  • The number of favorable outcomes added to the total number of outcomes.
  • The number of unfavorable outcomes divided by the total number of outcomes

What is the key difference between independent and dependent events?

  • The occurrence or nonoccurrence of one event does not affect the probability of the other event in independent events, while it does in dependent events. (correct)
  • The occurrence or nonoccurrence of one event affects the probability of the other event in independent events, while it does not in dependent events.
  • Independent events are always more likely to occur than dependent events.
  • Dependent events are more likely to occur than independent events.

What is the significance of feedback in shaping cue/criterion relationships?

  • Feedback is ineffective in shaping cue/criterion relationships regardless of the environment's complexity.
