Answer:
0.496
Step-by-step explanation:
The probability that a particular transistor be deflective is 0.03. This situation may be seen as a experiment-result situation. You may choose one of the transistors and find out if it is deflective.
Be r the probability that a transistor selected be deflective. Be R the probability that the transistor selected don't be deflective; it is easy to note that R=1-0.03, due to the total of possibilities for the single experiment are two: deflective or not deflective.
If a single result has a probability of p, the probability P that the same result be obtained n times is:

So, the probability that none of the transistors be deflective is:

The correct answer for this question is 4.
We have to bear in mind that any number should be less than 5 to make the square root be an imaginary number.
Starting with 4
= square root (4 - 5)
= square root (-1)
= imaginary
