Answer:

45 times

Step-by-step explanation:

There are nine pink sections and 11 sections total. The probability of landing on a pink section is 9/11.

Multiply the probability by 55

[tex]\frac{9}{11}[/tex] × [tex]\frac{55}{1}[/tex]

Cancel the 11 and 55. The 11 becomes a 1 and 55 becomes a 5

[tex]\frac{9}{ 1}[/tex] × [tex]\frac{5}{1}[/tex]

45
