PROBABILIYT THAT EXACTLY ODD NUMBER TURNS UP AMONG THE THREE OUTCOMES IS 1/8.

Probability of getting odd number in first chance = 2/6 = 1/3

as 3 favourable outputs (1,3,5) out of 6 possible outcomes.

so PROBABILIYT THAT EXACTLY ODD NUMBER TURNS UP AMONG THE THREE OUTCOMES IS 1/2 * 1/2 *1/2 = 1/8

Prob. of getting a ODD No. in the first chance=3/6=1/2
Prob. of getting a ODD No. in second time is =1/2
Similarly for the third time =1/2
Thus, in aggregate the probability of getting odd no.in all the time =1/2*1/2*1/2=1/8

there are 3 odd numbers1,3 and5.
probabilty if 1 that it will come 3 time=1/3*1/3*1/3=1/27
same for 3 and 5.
so total probability=1/27+1/27+1/27=3/27=1/9

...as i knw..if i m wrong please give right solution
