hour on exactly one
subject </h3>
Question Parameters:
The amount of study time that Actuary Tong will spend on each exam in a day follows a continuous random variable that ranges from 0 to 1 hour.
Generally, the equation for the Probability of spending at least half an hour on a subject is mathematically given as
P(A)= (1 – 0.5)/(1 – 0)
P(A)= 0.5
Hence, the Probability of spending at least half an hour on exactly one subject is mathematically given as
P(1)=2C1 * 0.5 * 0.5
P(1)= 0.50
