How do you do probability on numbers

First, the denominator is the amount of subjects (for example colors). Say the question is find the probability of red. Say there is 4 blue dots, 9 red dots, 2 yellow dots, and 3 orange dots. The denominator would be 18 (the amount of dots). The numerator would be 9 because that is how many dots that were red are there. The answer would be 9/18 = 1/2. I hope his helps :)

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.

i got 86 for this

hope this !
