Very likely

hey it is “UNLIKELY”

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.

impossible

mistake

*avg no. of arms must be(slightly) 0.5 (VERY LIKELY)

as P=(100+5)/130

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

i think certain… bcoz nthin s impossibl na

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

Very Likely.(mostly a person wid two arms or in any chance a handicaped with one complte arm)

avg arms<2

Unlikely, not impossible as people are born with more than 2 arms too.

IMPOSSIBLE

Certain … coz the avg must be below 2

and i will see a person with 2 arms just now …

likely

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

Very Likely ðŸ™‚

Very likely

(since average number of arms is less than 2 since there are many handicapped persons in the world)

impossible,……………how can it be?

impossible

Likley
