That looks right to me! I can't remember the answer exactly but that sounds familiar. I think I see where I went wrong in this now.= 136

Bump.2.
A 75 year old has a 50% probability of living for another 10 years.
A 75 year old has a 20% probability of living for another 15 years.
An 80 year old has a 10% probability of living for another 10 years.
What is the probability that an 80 year old will live for another 5 years?
I don't get it, what is stopping me from constructing a circle (cut in half) inside the square and saying that circle satisfies the problem? Are there any added constraints you didn't mention?
The diagram shows two semicircles inside a square of side length 1. The common centre of both semicircles lies on a diagonal of the square.
What is the shaded area?
Let \( P(a, a^2) \) be a point on the parabola \( y = x^2, a>0 \). Let \( O \) be the origin and \( (0,b) \) the y-intercept of the perpendicular bisector of line segment \( OP \). Find \( lim_{P \to O} b. \)
C, D, and T are all constants, although you don't know what they are. All possible placements of the T things in the drawers are equally likely.Well, i dont really understand the question completely, is it like C and D are constants while T is variable which takes all values from 1 to CD-1, and due to random placing, all are equally likely . Or is T also fixed(then i dont make sense of this)?
I don't have the answer, so what's your logic behind these guesses?Also is the answer 1/(CD-1) for all parts ? or maybe (CDcn)/2^(CD) ? where CDcn=CD!/(n! * (CD-n)! )
