The probability that a senior takes the bus to school every day, given that he or she has a driver’s license is 17%.

What is Probability?

Probability helps us to know the chances of an event occurring.

$\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}$

As per the rule of conditional probability, the probability that a senior takes the bus to school every day, given that he or she has a driver’s license can be written as,

P(Have License | Takes school bus)

   = (Probability the seniors have driver’s licenses and take the bus to school every day) / (Probability of Having a licenses)

  = 0.14 / 0.84

  = 0.16667 ≈ 17%

Hence, the probability that a senior takes the bus to school every day, given that he or she has a driver’s license is 17%.
