In a multiple choice question , there are 4 alternatives, of which one or more are correct. a candidare will get marks in question
only if he ticks all the correct answer. if the candidate ticks the answer at random but is allowed up to three chances to answer the
question , then the probability that he will get marks in the question
thank anonimnystefy
but how can you get it
thanks got it
i have a question if a plane ax+by+cz+d=0 intersect coordinate axis at A, B,C , then what is the valume formed by ABC
Yes got it
Thanks bobbym got it (above give process)
but how can you write it in your answer
thanks bobbym
but how can you get the answer
would you like to explain here
thanks bobbym got it
yes you are right
bobbym would you like to explain your tree diagram
thanks
thanks anonimnystefy but i did not understand in well manner
Three digit no. are formed then what is the probability that middle digit is largest
thanks bobbym,anonimnystefy
but how can i get this
yes answer given as
options
(1) 5/11 (2) 5/6 (3) 6/11 (4) 1/6
yes bobbym
explanation required
a six faced fair dice is tnown until 1 comes , then the probability that 1 comes in even no. of trails is
my solution
If
and are in A.P, ThenIf
; x is rationaland
; x is irrationalthen no. of values at which
is continuous isthanks anonimnystefy and dude
(triying to understand that)
no no got it
three no. are choosen from the set {1,2,3,4,......,2011}. then find the probability that they are
(1) three consecutive no. of an arithmetic progression
(2) three consecutive no. of an Geometric progression
i have edit my questions
yes bobbym fully got it
thanks
yaa i partially understand
i have last doubt
what is the meaning of equaly probable here
thank
Thanks bobbym (you are right)
sample space S={HH,HT,T1,T2,T3,T4,T5,T6}
Let B= event dice shows >4
and A=at least one tail
here n(B)= {T5,T6} and n(A)={HT,T1,T2,T3,T4,T5,T6}
So
So i have a doubt that why this is not a answer
yes how can i get it (post 2)
and where i have done wrong
yes bobbym you are right 2nd one is right
i have a question why 1 st answer is not right
consider the experiment of tossing a coin . if the coin shows head toss it again but if it shows tail then throw a dice then
find the conditional probability of the event 'the dice shows a no. greater then 4'. given that there is at least one tail
my solution ::
sample space S={HH,HT,T1,T2,T3,T4,T5,T6}
Let B= event dice shows >4
and A=at least one tail
So
but answer given is
So where i have done wrong
can anyone explain me
thanks
