find no. of real value of x for which
and are in Arithmetic progressionbut answer given is
options
(1) 7/288 (2) 23/504 (3) 23/252 (4) 7/144
yaa thanks to all i have got it
2 small square are choosen at random at random from a chess board then the probability that they have exactly one common vertex
thanks bobbym and dude got it
three no. are choosen from the set {1,2,3,4,......,2011}. then find the probability that the no. are in
(1) arithmetic progression
(2) Geometric progression
bobbym how can i get integer solution
thanks
a 3 digit no. is formed. then find the probability that this 3 digit no. is divisable by 9
if it is given that it is divisable by 11
no no got it
thanks
thanks bobbym
i have searched in my book in topic (prime factorization)
thanks bobbym
would you like to explain your answer
thanks bobbym . is there is any link in which all things are present
thanks bobbym got it
thanks bobbym
but how you get these things
three non collinear points are marked in a plane. find the probability of getting an obtuse angled triangle by joining them.
find
thanks bobbym i want explanation
would you like to explain it to me
Let N be a no. of 4 digit numbers a b c d . where the digit satisfy the condition
(i) a<b<c<d
(ii) a>b>c>d
(iii) a<=b<=c<=d
(iv) a>=b>=c>=d
these are 4 different cases
then find total no. N in each cases
5 different marbles are placed in 5 different boxes randomly. find the probability that exactly 2 boxes remain empty
given each box can hold any no. of marbles
a pair of no. is picked at random (without replacement) from a set {1,2,3,5,7,11,12,13,17,19}.The probability that the no. 11
was picked given that the sum of no. was even, is nearly
thanks dude , now i have a doubt
whether 0 is even no. or odd no.

We are equating volumes the surface of the inner sphere does not have a volume. It does not have any depth. It is two dimensional therefore no volume.
integer a,b,c,d not necessary distinct, are choosen independently and at random from the set
S={0,1,2,3,4,5........,2006,2007}. then find the probability that |ad-bc| is even
bobbym i want more explanation
thanks
thanks bobbym and Dude
but for radius of 1unit, If we take a sphere of radius 1/2
than the point which is exactly on that sphere(1/2 radius sphere) . then these point are equal distance from center of sphere of radius 1 and also equal distance from surface
