Question

An embedded sensor is used to monitor a neuron in a human brain. We monitor the
sensor reading for 100 ms and see if there was a spike within the period. If the person
thinks of flexing his knee, we will see a spike with probability 0.9. If the person is not
thinking of flexing his knee (due to background noise), we will see a spike with probability
0.01. For the average person, the probability of thinking of flexing a knee is 0.001 within
a given period. 

(a) What is the probability that we will measure a spike?

(b) What is the probability that the person wants to flex his knee, given that a
spike was measured?

(c) What is the probability that the person wants to flex his knee, given that no
spike was measured?
