The probability of selecting a receipt of more than $25 is 0.33.
What is a probability?
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
For the given situation,
The amount on receipts in $, S= { 15,25,17,23,37,28 }
⇒ [tex]n(s) = 6[/tex]
The amounts are grouped as more than $25 and less than $25.
The event is the amount on receipt more than $25, [tex]e = (28,37)[/tex]
⇒ [tex]n(e)=2[/tex]
The formula to find the probability of an event,
[tex]P(e)=\frac{n(e)}{n(s)}[/tex]
⇒ [tex]P(e)= \frac{2}{6}[/tex]
⇒ [tex]P(e)=\frac{1}{3}[/tex]
⇒ [tex]P(e)=0.33[/tex]
Hence we can conclude that the probability of selecting the receipt of more than $25 is 0.33.
