Help 20

 

John and Ted have a reputation for being late to events. If John is late 20% of the time, and Ted is late 40% of the time, what is the probability that both John and Ted will be on time? Show your work or explain how you got your answer.

John's probability to be on time: 100% - 20% = 80% or 0.8.

Ted's probability to be on time: 100% - 40% = 60% or 0.6.

 

To find the probability that both will be on time, we multiply the two probabilities. \(0.8\cdot0.6 = 0.48\). The answer is \(\boxed{48}\)%.

The answer is 48%. The Latex for the percent sign does not work.
