Find the probability that John will have company on the way to school.

Identify the scenarios where John has company.

John will have company if he rides with friends or if his parents take him. These are the only two scenarios where he is not alone.

Calculate the probability of each scenario.

  • Probability of riding with friends: \( P(\text{Friends}) = 0.08 \)
  • Probability of parents taking him: \( P(\text{Parents}) = 0.49 \)

Add the probabilities of the two scenarios.

The total probability of John having company is the sum of the probabilities of the two scenarios: \[ P(\text{Company}) = P(\text{Friends}) + P(\text{Parents}) = 0.08 + 0.49 = 0.57 \]

The probability that John will have company on the way to school is \(\boxed{0.57}\).

The probability that John will have company on the way to school is \(\boxed{0.57}\).
