The random variable in this experiment is the number of days out of 3 that Pete catches fish. This is because it is the variable that is being measured and can take on different values, specifically 0, 1, 2, or 3. The probability of catching fish (0.8) is not the random variable as it is a fixed probability. The number of days (3) is not the random variable as it is constant and does not vary. The number of fish in the body of water is not being measured or varied in this experiment, so it is not the random variable.
