You get out on the street and see that there is heavy traffic. What is the chance you will get to your appointment on time

Respuesta :

Answer:

0.68

Step-by-step explanation:

According To the Question,

Let, H ⇒ "heavy traffic" & T ⇒  "get there on time".

Then, "half of the time there is heavy traffic" ⇔ P(H)=0.5.

  • Given, In the past, there has been heavy traffic and you have made it to your appointment within 30 minutes 34% of the time. This has to be taken to mean P(H and T) = 0.34.

Now, you are given that there is heavy traffic, so We need to find P(T I H).

 P(T l H) = P(H and T) / P(T)

P(T l H) = 0.34/0.5 ⇒ 0.68
