—radius is 1/2 the diameter so if the diameter is 6, the radius would be 3.
—the circumference is 2pier
so you would use your calculator and use the pie symbol or 3.14 and multiply 2*3.14*3 (3=radius for my example)
— the area is pie r^2
so you would multiply 3.14*3 squared

Researchers estimate that 21.5% of men and 17% of women smoke. 70.2/100000 men develop lung cancer and 50.5/100000 women 90% of
marishachu [46]
All the probabilities are given for the three different scenarios in men and women: people who smoke, people who develop lung cancer, and people who develop lung cancer who are also smokers. Then, these are even classified in terms of gender.

But the final question only has to do with men who are smokers that develop lung cancer. So, I think all the other data are only there for the purpose of red herring. The answer is already there, but you just have to find it among the others. First, you ignore all the probabilities involving women because we only want the men. Then, you find the probability of men that have lung cancer being smokers. The answer is 90%.

A number cube is tossed and a spinner is spun. What is the probability of getting a 3 or 4 on the number cube and not getting 8
Rufina [12.5K]

Answer:

7/24

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
