hey it is “UNLIKELY”
January 31st, 2011 - 22:25
hai friends, there is every possibility the man u met next has above average number of arms( ammunation,gun ,pistol,revolver etc)

Hey !!! ……There are two things to notice.
Less than avg arms=Either 1 arm or No arm.
Above avg arm=Both arms.
total conditions=Either 1 + No arm + Both arm.
Requirment is Above avg arms means >1
so mathmetically its = 1/(1+1+1)=1/3=33.33% MEANS <50%
Hence ans is UNLIKELY…..

Unlucky

It is quite possible so the answer should be very likely.
August 26th, 2010 - 21:32
impossible
August 26th, 2010 - 00:29
mistake
*avg no. of arms must be(slightly) 0.5 (VERY LIKELY)
as P=(100+5)/130
August 26th, 2010 - 00:34
well i donno why the comm. doesnt showing less than sign
so here it is again
avg no. of arms must be(slightly) less than 2
hence probability must be greater than 0.5(very likely)
as P=(100+5)/130
August 26th, 2010 - 16:15
i think certain… bcoz nthin s impossibl na
August 26th, 2010 - 00:25
lets assume….there are 100 ppl with two arms
25 ppl with one arm
and 5 ppl with more then two arms
now as 25 is > 5
then avg no. of arms must be(slightly) 0.5 (VERY LIKELY)
as P=(100+5)/130
August 25th, 2010 - 00:54
Very Likely.(mostly a person wid two arms or in any chance a handicaped with one complte arm)
avg arms<2
August 24th, 2010 - 12:02
Unlikely, not impossible as people are born with more than 2 arms too.
August 24th, 2010 - 00:41
IMPOSSIBLE
August 23rd, 2010 - 21:32
Certain … coz the avg must be below 2
and i will see a person with 2 arms just now …
August 23rd, 2010 - 17:40
likely
August 23rd, 2010 - 16:20
We know that the avg no. of arms is surely less than 2 ….
let us suppose it is 1.8… it is close to 2 becoz there are vry less no of handicapped as compared to normal…
now there is a 50% probability that either the next person is below 1.8 or above 1.8….
hence among the given options
likely is the appropriate ans..

Hey Gujjar,
Well explained. Though “very likely” is the correct answer
August 23rd, 2010 - 13:52
Very Likely
August 23rd, 2010 - 13:46
Very likely
(since average number of arms is less than 2 since there are many handicapped persons in the world)
August 23rd, 2010 - 13:33
impossible,……………how can it be?
August 23rd, 2010 - 11:57
impossible
