Hi
A survey of 978 investors asked how often they tracked their portfolio.
Daily               220
Weekly              280
Monthly             274
Couple of times/year 141
Don’t track           63 
total                978
What is the probability that an adult investor tracks his or her portfolio daily
According to this survey, one would expect that probability to be:
 P ( daily) = 220/978 = .225
