Step-by-step explanation:
Given in the question,
a number cube is tossed and a spinner is spun.
Cube have 6 in numbers
1 2 3 4 5 6
probability of having 3 or 4 = 2/6
= 1/3
Spinners are commonly made with 6, 8, 10 and 12 flat surfaces.
If a spinner has 8 flats then you have a 7/8 chance of not getting an 8.
Probability of getting a 3 or 4 on the number cube and not getting 8
"and" mean multiplication
7/8 x 1/3
7/24
Ответ:
P = 0.2917
Step-by-step explanation:
There are 6 possible results for the cube numbered {1, 2, 3, 4, 5, 6}
There are 8 possible results for the spinner.
Then the amount of results that can be obtained from the combination of these experiments is:
Then, we seek to obtain a 3 or a 4 and in the spinner any number other than 8.
exist
Then the probability sought is:
