Thanks Thickhead.
a train consists of n carriage, each of which may have a defect with probability p.all the carriage are inspected
, independentely of one another,by two inspectors, the first detects defects(if any) with probability p1 and
the second with probability p2. if none of the carrage is found to have a defect,the train departs. find the probability
of the event; ' the train departs with at least one defective carriage.
the number of ways of dividing
men and women into couples each consisting of a man and a woman isYes Bobbym(Administrator.)
Total no. of ways by which we can arrange the word
in a grid such that no same letter occur in each row and now row remain empty.the number of ways of dividing 15 men and 15 women into 15 couples each consisting of a man and a woman is
Thanks Admin and anonimnystefy got it
I have solved (1) one
19! contain factor of 9. so R.H.S must be divisible by 9.
So for divisibility by 9., sum of digit must be divisible by 9.
So
so a = 1 .
But I did not understand how can i solved (ii) one
Thanks
(1) If
Then value of is(2) If
. Then value of isIt's the number of paths from A to F times the number of paths from G to B.
To anonimnystefy I did not understand it
why we minus it.
please explain it to me
Thanks
To Admin (Bobbym) i did not understand it
It is just adding up all the paths in the lattice around the missing intersection.
Thanks
To anonimnystefy I have understand
(Which is Total no. of path from A to B, If There is a connectivity between F to G)
but Did not understand
Would you explain it to me.
Thanks
Thanks anonimnystefy
To friends I have edited by Question.
Thanks bobbundy I am Getting 28
Thanks Bobbym would you like to explain me to it.
Integer values of
for which is a perfect square.How can i solve Differential equation
To anonimnystefy I have edited it.
I am Getting 12. To Admin. (bobbym) is it right or not
Thanks
Would you like to explain me analytical answer.
I also tried for that method but could not get it.
(But I like yours Counting method.)
Yes Bobbym I need upper bond.
Thanks Bobbym would you like to explain it to me, Thanks
