ok dude look just leave those topics in which u are strong and do pastpapers from 2007 onwards of those questions in which you are weak. im doing the same but i started from 2001 since i started early
I still dont get it :SP(20-12<X<20+12)=.94
standardize and solve
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 helpsI still dont get it :S
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 *4c41)Ten people travel in 2 cars,a saloon and a Mini.If the saloon has seats for 6 and the Mini has seats for 4,find the number of different ways in which the party can travel,assuming that the order of seating in each car does not matter and all the people can drive. Ans- 210
2)I have seven fruit bars to last the week. 2 are apricot, 3 are fig and 2 peach. I select one bar each day. In how many different orders can I eat the bars? Ans-210
If I select a fruit bar at random each day,what is the probability that I eat 2 apricot ones on consecutive days? Ans -2/7
Can someone try ...mmm not gtn the answer

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 mostlynov2010 variant 3 q1. Can anyone help me please?
