Final answer:

Among the options given for probable outcomes, the choices that are not valid probabilities because they fall outside the 0 to 1 range include 1.65, -0.44, 125%, and -3/5. The correct answer is option d.

Step-by-step explanation:

The question pertains to identifying an outcome that cannot be considered a valid probability outcome from a list of options. Probability outcomes are values that denote the likelihood of an event occurring, which can never be less than 0 or more than 1. Thus, any probability value must be between 0 (impossible event) and 1 (certain event), inclusive.

Let's examine the options given:

  • a) 2/3: A valid probability (between 0 and 1)
  • b) 0.63: A valid probability (between 0 and 1)
  • c) 1.65: Not valid, it's greater than 1
  • d) -0.44: Not valid, it's less than 0
  • e) 1: A valid probability (certain event)
  • f) 125%: Not valid in decimal form, it's greater than 1 (1.25)
  • g) 24%: Valid as a decimal (0.24)
  • h) -3/5: Not valid, it's less than 0
  • i) 0: A valid probability (impossible event)

Therefore, the options that cannot be considered valid probability outcomes are c) 1.65, d) -0.44, f) 125%, and h) -3/5. Since the question asks to identify one option that cannot be considered a probability outcome, any one of these invalid options would be a correct choice. However, if forced to choose one, option d) -0.44 would be correct as it indicates a negative probability, which doesn't exist in the context of probability theory.
