Answer:
Step-by-step explanation:
Notice that the cross section is parallel to the base. So, if the cross section is a circle, then the base is also a circle.
Then, we just need to find all figures that have a circle at the bottom. The figures are a cylinder and a cone.
Therefore, the right answers are A and C.
Answer:
A. Cylinder
C. Cone
Step-by-step explanation:
Both a cylinder and a cone are three dimensional shapes that contain a circle as the base. If a cross section is made parallel to the base, that means that it should have the same shape as the base. Since a pyramid and cube both have straight edges, it would not be possible to form a circle from a parallel cut to the base, so the only options are cylinder and cone.
The probability of randomly picking out a red marble is 1/5
To determine the probability of randomly picking out a marble and it being red, we need to consider the total number of marbles and the number of red marbles.
Total marbles = 5 green + 3 blue + 2 red = 10 marbles
Red marbles = 2
So, we have
Probability = (Number of favorable outcomes) / (Total possible outcomes)
This gives
Probability = (Number of red marbles) / (Total marbles)
By subsituition
Probability = 2/10 = 1/5
Hence, the probability of randomly picking out a marble and it being red is 1/5

Answer:
1/5
Step-by-step explanation:
Since there are 2 red marbles and since there are a total of 10 marbles, the probability is 2/10. This simplifies to 1/5. So the probability of picking a red marble is 1/5.
