A Practice

See Problem 1.

You spin the spinner below, which is divided into equal sections. Find each probability.

A circle with a spinner at the center is divided into 10 sections numbers 1 through 10.

  1. P(4 or 7)
  2. P(even or red)
  3. P(odd or 10)
  4. P(3 or red)
  5. P(red or less than 3)
  6. P(odd or multiple of 3)
  7. P(7 or blue)
  8. P(red or more than 8)
  9. P(greater than 6 or blue)

See Problem 2.

You roll a blue number cube and a green number cube. Find each probability.

  1. P(blue even and green even)
  2. P(blue and green both less than 6)
  3. P(green less than 7 and blue 4)
  4. P(blue 1 or 2 and green 1)

See Problem 3.

You choose a tile at random from a bag containing 2 A's, 3 B's, and 4 C's. You replace the first tile in the bag and then choose again. Find each probability.
