What is the probability that the next person surveyed is very prepared?
Response
Frequency
Explanation / Answer
Probabilty of next response being very prepared is independant of all previous responses.
So, it must be equal to probability of very prepared calculated from frequency distribution.
P(very prepared) = number of responses as very prepared / total number of responses.
= 262/2206
= 0.118
