the event is one of R1,R2,R3,R4,R5,R6, of which 3 out of 6 are even, so
P(even|red) = 3/6 = 0.5
This is the probability of red given even. Given even has occured means that13. P(red | even) =??
the event is one of R2, R4, R6, W2, W4, of which 3 of the 5 are red, so:
P(red|even) = 3/5 = 0.6
Like the others, identify the restricted sample space specified by the14. P( <4 | odd) = ??
restriction that the event is known to be even, and compute the prob on
this restricted sample space that the tag number is <4
