Use the image to answer the question.
A circular dial is divided into 10 equal parts from the origin toward the circumference. The parts are labeled clockwise from 1 to 28 in increments of 3. Beginning directly to the right, they are marked as 1, 4, 7, 10, 13, 16, 19, 22, 25, and 28. A needle is fixed vertically at the center, with the arrow pointing directly upward to the line between 22 and 25 at the top center of the dial.
If this spinner is to be spun once, how likely will it stop on a multiple of 9?
There are three multiples of 9 on the spinner - 9, 18, and 27. Out of the 28 possible outcomes, 3 are multiples of 9. Therefore, the probability of the spinner stopping on a multiple of 9 is 3/28.
Is it unlikely to happen or likely to happen or certain to happen or impossible to happen?
It is considered unlikely to happen since the probability is less than 50% (3/28 is approximately 0.107).
There are 25 balls in a jar. Twelve (12) balls are red, 10 balls are blue, and 3 balls are white. Which of the following describes the likelihood of randomly picking a white ball?(1 point)
Responses
impossible
impossible
likely
likely
very unlikely
very unlikely
less likely than not
The likelihood of randomly picking a white ball is "very unlikely" since there are only 3 white balls out of 25 total balls, making it less likely compared to the red or blue balls.
