S>0;t>0 Example Suppose the number of miles a car can run before its battery wears out follows the exponential distribution with mean = miles If the owner of the car takes a 5000mile trip what is the probability that he will be able to complete the trip without having to replace the battery of the car?.

P = i=1 hv,x ii hx i,x ii x i Note that if {x 1,,x n} is an orthonormal basis, then we have the simpler expression p = i=1 hv,x iix i Also in the special case where S is spanned be the single vector x 1, then p is just the usual orthogonal projection of v onto S, which is the line spanned by x 1 Now we can prove the main theorem of. 2 Independent Random Variables The random variables X and Y are said to be independent if for any two sets of real numbers A and B, (24) P(X 2 A;Y 2 B) = P(X 2 A)P(Y 2 B) Loosely speaking, X and Y are independent if knowing the value of one of the random variables does not change the distribution of the other ran.

How do we jointly specify multiple rvs, ie, be able to determine the probability of any event involving multiple rvs?. M672F14Sol64 with equality if and only if T(v) = 0 However, if T has a null space containing some v 6= 0, then P V (v;v) = 0 for that v, which contradicts the de nition of the inner product Thus for P V as de ned to be an inner product, T must not have a nonzero null space, so T must be onetoone. 2 So we can can write p(x) as a linear combination of p 0;p 1;p 2 and p 3Thus p 0;p 1;p 2 and p 3 span P 3(F)Thus, they form a basis for P 3(F)Therefore, there exists a basis of P 3(F) with no polynomial of degree 2 Exercise 2 Prove or give a counterexample If v.

P x V/T = a constant (for a given mass of gas) This can be expressed in generalised form for calculations based on an initial set of conditions 1 (1) changing to a new and final set of conditions 2 (2) for a given mass of gas, giving the combined pressure–volume–temperature gas. V = (nR/P) * T V = constant * T V T (Charles's law) If the temperature and pressure are held constant then PV = nRT V = n * (RT/P) V = constant * n V n (Avogadro's law) A very common situation is that P, V and T are changing for a fixed quantity of gas ;. PV = nRT (PV)/T.

Let’s say that x represents birds on a lake, and so P(x) specifies ducks, and Q(x) specifies geese ∀x P(x) ∨∀x Q(x) says that for the birds on the lake, either all of them are ducks, or else all of them are geese But in this situation, the lake.

P(k) = P(X = k), −∞ < k < ∞, for integers k 1 − F(x) = P(X > x) is called the tail of X and is denoted by F(x) = 1 − F(x) Whereas F(x) increases to 1 as x → ∞, and decreases to 0 as x → −∞, the tail F(x) decreases to 0 as x → ∞ and increases to 1 as x → −∞. P(X = x) = n C x q (nx) p x, where q = 1 p p can be considered as the probability of a success, and q the probability of a failure Note n C r (“n choose r”) is more commonly written , but I shall use the former because it is easier to write on a computer It means the number of ways of choosing r objects from a collection of n objects. P{X > b a}/P{X > b} = e −λ(ba) /e −λb = e −λa Thus, conditional law of X − b given that X > b is same as the original law of X Lecture Memoryless property for geometric random variables Similar property holds for geometric random variables.
