Answer:
68%
Step-by-step explanation:
Probability of occurrence of Event v = P(v) = 28% = 0.28
Probability of occurrence of both Events v and Event w together = P(v and w) = 19% = 0.19
We have to find what is the probability that event w occurs with event v given that event v occurs on a Tuesday. This is a conditional probability. In other words we have to find what is the probability of event w given that event v occurs of Tuesday. i.e we have to find P(w|v)
The formula to calculate this conditional probability is:
Using the given values, we get:
Therefore, the probability that even w will occur with event v given that event v occurs on Tuesday is 68%
Step-by-step explanation:
this is only what i got from this question. it may be the only thing we need to do.. or not. but this step is correct for sure
