As given in the question ( Machine X takes 2 days longer) So I put Machine Y takes D days and Machine X takes 2+D days......... By doing...

I did this in this manner and cant see why the book has a different answer : Number of spots : 3 Number of actresses : 5 Spot 1 Spot 2 Spot 3 J H X X J H H X J J X H X H J H J X Prob of (J and H)= (1/5)*(1/4)+ (1/4)*(1/3)+ (1/5)*(1/3)+ (1/5)*(1/3)+ (1/4)*(1/3)+ (1/5)*(1/4).=== 2/5. I cant see what i...

Got it. The equation is correct. 5t^2 -14t-24=0 When ever I see the co-efficient of t^2>1 - I just go for roots of quadratic = (-b +or - sqrt ( b^2-4ac))/2a The mistake I was making before was that the value of c in this equation is not 24 but -24. and that will give one of the roots as 4 and tha...

Tim, The line which reads SPOT 1....SPOT3 are the columns/slots that represent the vacancies for the roles for the actresses. And J and H stand for the actresses names- Julia and Hollie if i am not wrong. SPOT 1....SPOT2....SPOT3 J.............H...........X This means that Julia was chosen first for...

Yep I got B as well. Let X be the population of men and women who are at or above 65 years. X= A + B. Where A is men over or at 65 B is women over or at 65. The questions asks wether at-least 10/100 ( A+B) are employed. From 2 we know : 20/100 (A) + 10/100 (B) are employed. So now the question being...
