Answer:
1.3125
Step-by-step explanation:
Given that our random variable follows a Poisson distribution
Evaluate the formula at
#since
The mean and variance of the Poisson distributed random variable is equal to :
#By property variance:
The expectation is 1.3125
Answer:
B. The problem involves a combination because the order in which the letters are selected does not matter.
Step-by-step explanation:
Computation technique is a method of statistics to find possible ways of combination. In computation technique it is assumed that order does not matter and letters will be selected at random. Permutation is a statistics technique to find possible ways of combination when the order does matter. Permutation technique cannot be used when order does not matter.
This is because 2÷3 = 0 . Six repeating but the Calculator rounds the last 6 to 7 because I can't fit all the repeating sixes in one calculator
Reflexive Property=For all real number X,X=X
A number equals itself
Addition Property=For all real number X,y & Z,. if
X=Y then X+y=y+Z
Subtraction Property=For all real number X,Y And Z if X=y then X-Z=y-Z.
