Answer:
The probability that a vehicle would be involved in a tire-related accident is

Explanation:
We need to calculate the probability that a vehicule would be involved in a tire-related accident.
We know that, given a tire-related accident (TRA), the probability of it being deadly (D) is 0.05. That is:

We also know that the probability of being involved in a deadly tire-related accident is 0.000004 . We can express that as the probability of having a TRA multiplied by the probability of it being deadly:

Merging the two expressions we have:
