When а meteоrоid enter Eаrth’s аtmоsphere, it is called a(n) ____________.
Prоblem 1 (25 pts) Let A{"versiоn":"1.1","mаth":"A"} аnd B{"versiоn":"1.1","mаth":"B"} be two events in a probability space ((mathcal{S},mathcal{F},P)). Is it true that P(AB)=P(A)-P(B){"version":"1.1","math":"P(AB)=P(A)-P(B)"}? Why or why not? As a reminder, (Abackslash B={omegain mathcal{S}:omegain A, omega notin B}). Problem 2 (25 pts) Consider a random experiment with sample space S{"version":"1.1","math":"S"} = {1, 2, 3, 4, 5, 6}, where the outcomes in S{"version":"1.1","math":"S"} are all equally likely. Let A{"version":"1.1","math":"A"} and B{"version":"1.1","math":"B"} be independent events. Assuming that A{"version":"1.1","math":"A"} has four elements, what values can B{"version":"1.1","math":"B"} take, where B{"version":"1.1","math":"B"} is the number of elements in B{"version":"1.1","math":"B"}? Problem 3 (25 pts) Consider two probability measures P1{"version":"1.1","math":"P1"} and P2{"version":"1.1","math":"P2"} defined on the same event space (cal F). Under what conditions on the real-valued constants a1{"version":"1.1","math":"a1"} and a2{"version":"1.1","math":"a2"} is the function (a_1 P_1(A) + a_2 P_2(A), forall Ain cal{F}), a valid probability measure? Problem 4 (25 pts) A coin is tossed with P(H)=P(T)=12{"version":"1.1","math":"P(H)=P(T)=12"}. If the coin comes up heads, you lose 2 dollars. If it comes up tails, you are equally likely to win any amount of money in (0, 10) dollars, i.e., any real number between 0 and 10 dollars. Let X{"version":"1.1","math":"X"} be the amount of money you win. Find the cumulative distribution function of X. Note that X is negative if you lose money.
