______________________________
Explanation:
______________________________
Looking at the answers:
______________________________
 we know that 4² = 16 ; and 5² = 25 ;

So:  √16 = 4  ;  and √25 = 5.

So:  √21 must be between √16 and √25 ;

That is: √21 must be between 4 and 5 ; which is answer choice:  [A] .

At a manufacturing plant where switches are made, it is a known fact that 2% of all switches are defective. If two switches are
olchik [2.2K]

Answer:

The probability that exactly one switch is good is

P(x) =0.0392

Step-by-step explanation:

The probability that a switch is defective is:

P(D) = \frac{2}{100} =0.02

The probability that a switch is not defective is

P(D') = 1-P(D)=0.98

Therefore, if two switches are selected, the probability that exactly 1 is good is:

P(1=1)=P (D) P (D ') + P (D') P (D)

P(x)=(0.02)(0.98) + (0.98)(0.02)

P(x) =0.0392
