Every evening before the end of preps, Eunice either reads a novel or solves a mathematical problem. The probability
that she reads a novel is 4/5.If she read a novel, there is a probability of 3/4 that she will fall asleep. If he solves a mathematical problem, there is a probability of 1/4 that she will fall asleep. Sometimes the teacher on duty enters Eunice’s classroom. When Eunice is asked whether she had been asleep, there is a probability of only 1/5 that she will
admit that she had been asleep and a probability of 3/5 that she will claim to have been asleep when she had not been asleep
By use of a tree diagram, find the probability that
a) She sleeps and admits
b) She sleeps and does not admit
c). She does not sleep but claims that she had been asleep
d). She does not sleep and says that she has not been asleep
