There are different levels of classification when it comes to numbers. The general classification is between real numbers and imaginary numbers. Imaginary numbers are those with 'i' in them which is equal to √-1. Next, real numbers can be classified as rational or irrational. Irrational numbers are those that can't be expressed into fractions. Lastly, rational numbers are classified into integers and fractions.
Answer:
table:
.1, .25, .35, .2, .1
p(x=4) = .1
p(x<2) = .35
p(3≤x≤4)= .55
1.95, 1.12
Step-by-step explanation:
this is kind of hard to read, but i think i've got it
mean:
0*.1+1*.25+2*.35+3*.2+4*.1= 1.95
The second moment:
0²*.1+1²*.25+2²*.35+3²*.2+4²*.1= 5.05
the variance is the second moment minus the first moment squared (first moment is the mean) and then the standard deviation is the square root of the mean
5.05-1.95²= 1.2475 √1.2475= 1.1169 or 1.12
