The figures that can have a triangle as a two-dimensional cross section are (4) I, III, and IV, only
<h3>How to determine the figures?</h3>
The cross-section of three-dimensional figures are as a result of slicing the figure along its axis.
- When the cube is sliced with its plane, it gives a triangle face
- When a cone is sliced vertically, it gives a triangle face
- One of the faces of a square pyramid is a triangle; so it has a triangle face
Hence, the figures that can have a triangle as a two-dimensional cross section are (4) I, III, and IV, only

The probability of three independent events happening one after the other is the multiplication of the probability of the single events.
The probability of spinning an odd number is 5/10=1/2, because there are 5 odd numbers (1,3,5,7 and 9) out of the 10 numbers from 1 to 10.
The probability of spinning a number less than 4 is 3/10, because there are 3 numbers (1,2 and 3) that are less than 4 out of the 10 numbers from 1 to 10.
The probability of spinning a 7 is 1/10, because you only have one good outcome out of 10.
So, the probability of winning the game is
Answer:
a) 490
b) 240
Step-by-step explanation:
b) It is convenient to answer part B first.
The number owning only a fax will be the number owning a fax less the number that own both a fax and a copier:
420 -180 = 240 . . . . number owning only a fax
__
a) The number owning one or the other will be the number owing a copier (which includes those owning both) plus the number owning only a fax:
250 +240 = 490 . . . . number owning either

If you want to work part A first, then you need to use the relation ...
n(A∪B) = n(A) +n(B) -n(A∩B)
