originally there were 25 odds and 25 evens,
the 5 numbers already drawn are all odd,
so there remains:
25 evens and only 20 odds
so for the next draw:
prob(odd) = 20/45
prob(even) = 25/45
so what do you think?
in lotto draw balls 1-50 mixed together. machine randomly selects numbers 13,11,7,27,41. is the 6th number drown
A. more like to be odd than even
b. more likely to be even than odd
c. equally likely
i could not decide, as long as there even and odd numbers, there is a possibility to draw any. but, since now there is 25 even and 20 odd numbers are in the machines, maybe even is more likely? (25 out of 45 and for odd 20 out of 45.. ) any insights?
