Adomino is a rectangular tile composed of two squares. an integer is represented on both squares, and each integer 0-9 is paired with every integer 0-9 exactly once to form a complete set. a $\textit{double}$ is a domino that has the same integer on both of its squares. what is the probability that a domino randomly selected from a set will be a $\textit{double}$? express your answer as a common fraction.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
