a) the probability that at least 1 doesnt use a computer at work Because the question asks for at least 1 that doesn't we have to do the opposite complement. P(E)=1-P(complement) Probablity of not using computer(NUC)=1 - Probability of using computer P(NUC)= 1-P(UC) P(UC)= 0.72 P(using computer 5 times)=(0.72)(0.72)(0.72)(0.72)(0.72) or (0.72)^5=0.19349 P(NUC)= 1-(0.72)^5= 0.807 b) The probability that all 5 use a computer in their jobs P(C)=P(C*C*C*C*C)=(0.75)(0.75)(0.75)(0.75)(0.75)=(0.75)^5=.194

Kindly help and its very urgent

Are you sure ?? I mean is something wrong in statement

Thank u So answer will be (1/2,1/2,-1/2)

Thank you

I got the x in terms of y And its y=root[(1+4y^2)/y^2] Its range should not be (- infinity ,+ infinity)

Sorry its x=root[(1+4y^2)/y^2] f^-1(y)=root[(1+4y^2)/y^2] f^-1(x)=root[(1+4x^2)/x^2 ] Where (1+4x^2)/x^2>=0 This inequality is true for any real values of x. So, its range should not be (- infinity ,+ infinity) Kindly check my solution again

Thanks

I mean how to solve

Okay. I have to only write how they are similar . Only reason. Not to solve and show . Is it possible that we can show it??

Okay Can you just confirm me following points I mean we just need to assume Principal=rs100, r=7.5%pa and time 1 year Then find simple interest= rs 7.5 Then all values except time is same and then we need to plot a graph

How? Please explain

I didnt get it

I dont understand what you have replied

Kindly reply anyone

Thanks
