This is the probability even given red. Given that red has occured that means

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
