If a hedgehog crosses a certain road before 7.00 a. m., the probability of being run over is 1/1. After 7.00 a. m., the corresponding probability is 3/4. The probability of the hedgehog waking up early enough to cross before 7.00 a. m., is 4/5 What is the probability of the following events:

a) the hedgehog waking up too late to reach the road before 7.00 a. m.

b) the hedgehog waking up too late to reach the road before 7.00 a. m.

c) the hedgehog waking up late and crossing the road in safety

d) the hedgehog waking up early and being run over

e) the hedgehog crossing the road in safety
