The experimental probability of spinning a 6 is 1/12, an even number is 1/2, a number less than 3 is 1/6, and spinning a 7 is 1/12, based on the bar graph frequencies.
Outcome | Frequency *---|---|
3 red | 4
3 blue | 0
2 blue, 1 red | 2
2 red, 1 blue | 4
The probability of each event can be calculated by dividing the frequency of the event by the total number of events (which is 12 in this case). For example, the probability of getting 3 red is 4/12 = 1/3.
Use the bar graph to find the experimental probability of the event.
The bar graph shows the frequency of each outcome. The probability of an event can be found by dividing the height of the bar for that outcome by the total height of all the bars. In this case, the total height of all the bars is 12. For example, the height of the bar for the outcome "3 red" is 4. So, the probability of getting 3 red is 4/12 = 1/3.
Spinning a 6
The probability of spinning a 6 is 1/12, because there is only one outcome that results in a 6 and there are 12 total possible outcomes.
Spinning an even number
There are 6 even numbers that can be spun (2, 4, 6, 8, 10, and 12). So, the probability of spinning an even number is 6/12 = 1/2.
Spinning a number less than 3
There are 2 numbers that are less than 3 (1 and 2). So, the probability of spinning a number less than 3 is 2/12 = 1/6.
Spinning a 7
There is only one outcome that results in a 7, so the probability of spinning a 7 is 1/12.
