IEE 380 Exam 1 QUESTIONS WITH 100% CORRECT ANSWERS/A+ GRADE
addition rule - ✔✔P(A u B) = P(A) + P(B) - P(A n B)
probability of A + probability of B - the intersection of A & B because (A n B) is
counted twice in P(A) + P(B)
analytic study - ✔✔Analytic studies are done to test specific hypotheses
Bernoulli PMF - ✔✔p(x) = p^x * (1-p)^(n-x)
Bernoulli Trial - ✔✔when a random process or experiment results in one of only
two mutually exclusive outcomes
Binomial PMF - ✔✔p(x) = (nCx)p^x * (1-p)^(n-x)
cause and effect - ✔✔Cause and effect refers to a relationship between two
phenomena in which one phenomenon is the reason behind the other
combination - ✔✔a selection of r items from a set of n where order does not
matter
nCr
continuous random variable - ✔✔a variable with an interval(either finite or
infinite) of real numbers for its range. its values are obtained by measuring
, electrical current and voltage
time
continuous sample space - ✔✔a sample space that contains an interval of real
numbers
Continuous Uniform pdf - ✔✔This is the simplest continuous distribution and
analogous to its discrete counterpart. If X has the Continuous Uniform
distribution:
pdf of X = f(x) = 1/(b-a) for a<x<b
cumulative distribution function - ✔✔A function giving the probability that a
random variable is less than or equal to a specified value.
Cumulative Distribution Function (CDF) - ✔✔cdf gives the probability that a
random variable will be less than or equal to specific values
the cdf for a random variable X may be expressed as F(X)=P(X<=x)
given the cdf for a random variable, the probability that an outcome will be less
than or equal to a specific value is represented by the area under the probability
distribution to the left of that value
discrete random variable - ✔✔a variable with a finite or countably infinite
range. its values are obtained by counting
addition rule - ✔✔P(A u B) = P(A) + P(B) - P(A n B)
probability of A + probability of B - the intersection of A & B because (A n B) is
counted twice in P(A) + P(B)
