Needed

a. the spinner has 4 colors, so there should be 4 possible outcomes

b. the spinner can land on the same color twice in a row, so there should be 16 possible outcomes

c. there are 4 possible colors for each spin, so there should be 8 possible outcomes

d. there are 6 combinations that are counted twice, so there should be half as many possible outcomes

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.
