the random variable X, representing the number of accidents in a certain intersection in a week, has the following probability distribution:

x: P(X=x), 0=0.20, 1=0.30, 2=0.20, 3=0.15, 4=0.10, 5=0.05

By the third day of a particular week, 2 accidents have already occurred in the intersection. What is the probability that there will be less than a total of 4 accidents during that week?
