A DIE IS ROLLED THREE TIMES THE PROBABILIYT THAT EXACTLY ODD NUMBER TURNS UP AMONG THE THREE OUTCOMES IS:
Read Solution (Total 4)
-
- 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 - 13 years agoHelpfull: Yes(5) No(1)
- 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 - 13 years agoHelpfull: Yes(4) No(0)
- 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 - 13 years agoHelpfull: Yes(0) No(2)
- I ALSO USED SAME APPROCH ....BT OPTIONS ARE 1/6,3/8,1/8,AND 1/2
AND IN QUESTION THEY ASKED EXACTLY ONE ODD NUMBER AMONG THE THHREE OUTCOMES..... - 13 years agoHelpfull: Yes(0) No(1)
