Answer:

480 times

Step-by-step explanation:

Given

[tex]n = 50[/tex] ---- total number of rolls

See attachment for complete question

Required

Times OO will appear in a roll of 2000 times

From the attached bar graph,

[tex]n(OO) = 12[/tex]

So, the occurrence of OO in 2000 rolls is:

[tex]OO = \frac{n(OO)}{n} * 2000[/tex]

[tex]OO = \frac{12}{50} * 2000[/tex]

[tex]OO = 0.24 * 2000[/tex]

[tex]OO = 480[/tex]
