    its very easy bro just think of it like this 32 teams play the first match but 16 get knocked out so hence the teams who have played only A SINGLE MATCH IS 16. then these 16 teams who survived play a second match of which 8 got knocked out hence 8 teams have played exactly two match. the...

    obviously its normal distribution because the mean is the center of all the data. s.d can be 6kg and mean can be 60. u will use normal because female students specially have even weights mostly

    q1 ) i have to select 6 ppl from 10 for the saloon hence 10C6 and now i have to select 4 from the remaining 4 for the mini and its 4C4. hence 10C6 *4c4 q2) You just have to arrange the fruit bars 7!/2!*3!*2!

    if X is the mean then X1 should be 20-12 and X2 should be 20+12 P(X1<X<X2)=.94 i hope this helps

    P(20-12<X<20+12)=.94 standardize and solve

    here assume X1 as the least time for the journey and X2 has the greatest time for the journey. P(X1<x<X2)=.34 standardize to get P(-z1<Z<z2)=.34 then u get 2fi(z)-1=.34 solve and get fi inverse of the value. make the standardized equation and use the value that u have got once positive and once...

    use the original value if its written in the qs that x follows a normal distribution if not then cc

    is it 2!*3p3? *A*A* * is the place where the ppl from area B will be placed and A is the place for the 2 guys from area A

    225/900 is the probability that P(x>1002) hence standardize and solve :)
