Well P(C) is product is even so if you list out the possibilities which are (12 14 16 21 22 23 24 25 26 32 34 36 41 42 43 44 45 46 52 54 56 61 62 63 64 65 66)http://papers.xtremepapers.com/CIE/...S Level/Mathematics (9709)/9709_s11_qp_63.pdf
4 ii part. littlecloud11 Jiyad Ahsan syed1995
how do i get P(C)??? isnt it supposed to be 3/6?

when do we use 6.5 incase of fewer/ lesser than 7 and when do we use 7?
I am really confused about this
so that what its called i called it continuety correctivityYou use continuity correction when you use a continuous function to approximate a discreet one. Like when you normal distribution to estimate a binomial. Example, In a sample of X data find the probability that < than 20 will have 51 feathers.

thats y my sir said it was wrong

2 part ii i get the working but my answer is coming 163.6 instead :/
how do you find the s.d?Did you get the standard deviation as 3.2? If you did then it's just (3.2)^2 * 15 which is 153.6
got it was a silly serror didnt realise sum(x-104.8)=0 -_-Did you get the standard deviation as 3.2? If you did then it's just (3.2)^2 * 15 which is 153.6

cc is only applied where there is a conversion from binomial to normalbut how do i tell the difference between such type of questions...i have seen many problems where we are supposed to find the probability of fewer than 75(for e.g.) and we use (75-mean)/S.D. to calculate it...
my teacher told me that whenever we have to add or subtract 0.5...we are told to use normal approximation in the question...but this is not always the case...
Thanks a ton...could you plz elaborate what you mean by conversion from binomial to normal...i am sorry i can do questions just fine but i don't really get what is meant by binomial, normal etc...can yu plz just give me an example question...i ll be very thankful..cc is only applied where there is a conversion from binomial to normal
how do you find the s.d?
i got the ans but i did it in a much longer way...found the sum of xsquare first and then from there on got the rest

how to get the sd in 5iii
thanks for any help
