There are some standard formulas that can be used to find the probability of the compound events. The formulas are basically applied for the union and intersection of these events. Answer and Explanation:1 Given that: {eq}P(A) = 0.5, \ P(B) = 0.6, {/eq} and {eq}P(A \...
Suppose that A and B are independent events such that P(A) = 0.40 and P(B) = 0.20. Find P(A∩B) and P(A∪B). Addition Rule of Probability under independent events If events A and B are given, the addition rule of probability defines the prob...
Probability:Probability is an important concept in the prediction of future events. It is the measure of the likelihood of occurrence of an event with a value from zero to one, inclusively. The zero probability is used for the impossible event and a probability of one is used for the ...
We h ave A=[{:( a+4,3b) ,( 8,-6):}](2xx2)"and" B=[{:(2a+2,b^(2)+2),( 8,b^(2)-5b):}](2xx2) Also, A=B By equality of matrices we know that each element of A is equal to the corresponding element of B, that is a(ij)=b(ij) for all i and j. a(11...
