Answer:
a) 0.03
b) 0.0004
c) 0.0001
Step-by-step explanation:
Probability that the sensor reports what is going on accurately = 0.97
Probability that the sensor gives a false alarm = 0.02
Probability that the sensor gives a miss = 0.01
(a) Probability that the sensor reports what is going on accurately = 0.97
Probability that the sensor will give incorrect report = 1 - 0.97 = 0.03
It could also be evaluated as the probability that the sensor gives either a false alarm or gives a miss = 0.02 + 0.01 = 0.03.
b) Probability of false alarms on one sensor = 0.02
Since the two sensors are independent of each other,
The probability that the reactor will be shut down because of simultaneous false alarms by both the first and second sensors
= 0.02 × 0.02 = 0.0004
c) Probability of a miss with one sensor = 0.01
Since the two sensors are independent of each other,
The the new probability that excessive radiation will be missed simultaneously by both the first and second sensors
= 0.01 × 0.01 = 0.0001
Hope this Helps!!!

Step-by-step explanation:
In 3 meters you have 118.11 inches.
the number of faces, edges and vertices the shape below has is 4, 4 and 6 respectively.
<h3>How to determine the number</h3>
It is important to note that according to Euler’s formula for any convex polyhedron, the number of Faces (F) and vertices (V) added together is exactly two more than the number of edges (E).
It is mathematically written as;
Face + vertices = 2 + edges
F + V = 2 + E
From the figure given, we can see that it is a kite
Number of vertices = 4
Number of faces = 4
2 + edges = faces + vertices
2 + edges = 4 + 4
2 + edges = 8
Edges = 8 - 2
Edges = 6
Thus, the number of faces, edges and vertices the shape below has is 4, 4 and 6 respectively.
