Let
be a probability that i-th light fails, where i=1,2,3. Then,
is the probability that i-th light remain bright.
<span>If the lights fail independently of each other, the probability that a string of lights will remain bright for two years is:
</span>
.
Answer:
b) perpendicular to the plane containing both vectors
Step-by-step explanation:
The cross product is perpendicular to both contributing vectors. Consequently, it is perpendicular to the plane containing them.
The triangle presented in the image has 2 axes of symmetry because it is only possible to divide it 2 times.
<h3>What are axes of symmetry?</h3>
The axes of symmetry are a concept of geometry that are classified into two groups:
- The plane axis of symmetry: This is an imaginary line that divides a figure into two parts, ensuring that the symmetrical points are at the same distance from it.
- The axis of axial symmetry: This is the symmetry around an axis, it is a point of translation and rotation in which all the semi-planes taken from a certain perpendicular bisector have identical characteristics.
According to the above, it can be inferred that the rectangle presented in the image has only two axes of symmetry.
