Probablity Question. very simple???

[nanosecond]

Based on his review of analogue years, our trade floor meteo guy predicts that the gulf coast will experience 4 severe hurricanes over the next 100 days. Provide a range of probabilities of 2 or fewer hurricanes, expressed as lower and upper bound??? :tiphat:

Strange question I don't know what "lower and upper bound" is in this case
I can give the probability of P(X<=2) = 0.2381.
