Statistics S1 Doubts

[B!(+)(+)dy $k(_)!!]

To be honest best way is to make list off all possible outcomes

Could you please solve it and post the image like u did previously please?

 

[B!(+)(+)dy $k(_)!!]

please elaborate,p<10 is given ,not p<8,2,so we'll consider p<8,2 as p<0??

No noooo.... I guess u confused...
First we'll find P(X<8.2) which is 0.5...
So therefore, X is binomially distributed with n=35 and p=0.5
So, mean = np = 35*0.5 = 17.5 and variance = npq = 17.5 * 0.5 = 8.75
So, X is normally distributed with mean 17.5 and variance 8.75
So now, u can find P(X<16) by normal distribution...
Note: Do take care of the continuity correction

how u come to know P(X<2) is 0.5.it isnt given in the data,......how will we then calculate p(X<2)/?

We don't have to calculate P(X<2) bro...
We have to first calculate P(X<8.2)

 

[abdul moeed rana]

there's still one more day,5th nov ko ha!!

yesss,writing ,istake
please ans my other questions

Could you please post the screenshot?
That'll be easier for me..

q5 plzz,
within 12 gof mean means???

It means that you have to find P(mean-12<X<mean+12)
So add and subtract 12 from mean and find the probability...
