Answer:
Step-by-step explanation:
Given that a shuttle launch depends on three key devices that may fail independently of each other with probabilities 0.01, 0.02, and 0.02, respectively.
Required probability = the probability for the shuttle to be launched on time
= Probability that all three do not fail
Since each key device is independent of the other
we have
prob that all three do not fail =

Answer:
x=-4 and x=2
Step-by-step explanation:
You are given the function
The zeros of the function are those value of x, for which
First, find x for which function is undefined
Now find points at which f(x)=0:
For both these values (x=-4 and x=2) function f(x) is defined, then x=-4 and x=2 are zeros of the function.
