Yes, sorry about that...

Mr. Doodle’s grade distribution over the past 3 years for a course in college algebra is shown in the chart below.

Grade Number

A 45

B 180

C 110

D 95

If Jane plans to take a college algebra course with Mr. Doodle, determine the empirical probability that she receives at least a B. I think it's 1.77777 ??
