Answer:

\frac{2}{3}

Step-by-step explanation:

In math, when dividing by fractions, you need to multiply by the reciprocal.

-\frac{2}{11} *-\frac{11}{3}

Then, you can cross-cancel the 11

-\frac{2}{1}* -\frac{1}{3}

And multiply. Negatives cancel each other out so you get:

\frac{2}{3}

help solve this problem Based on a​ poll, 62​% of Internet users are more careful about personal information when using a public
erma4kov [3.2K]

Answer

The probability that among four randomly selected Internet​ users, at least one is more careful about personal information when using a public​ Wi-Fi hotspot is 0.979.

Step-by-step explanation:

Since  62​% of Internet users are more careful about personal information when using a public​ Wi-Fi hotspot.

Therefore, the Probability of 62​% of Internet users are more careful about personal information when using a public​ Wi-Fi hotspot is, p=0.62.

We have to find the probability that at least one user is more careful about personal information when using wi-fi hotspot.

Probability of internet users are not more careful about personal information when using a public wi-fi hotspot, i.e q=1-p

q=1-0.62=0.38

Use Binomial Distribution, i.e,  P\left ( X \right )=^nC_xp^xq^\left ( n-x \right )

p=0.62, q=0.38, n=4.

Required Probability  P\left ( X\geq 1 \right )=P\left ( X=1 \right )+P\left ( X=2 \right )+P\left ( X=3 \right )+P\left ( X=4 \right )

or

P\left ( X\geq 1 \right )=1-P\left ( X=0 \right )

                                          =1-^4C_0p^0q^\left ( 4-0 \right )

                                          =1-4\cdot1\cdot q^\left ( 4-0 \right )

                                         =1-4\cdot \left ( 0.38 \right )^4

                                         =1-0.02085136=0.97914864

Therefore, the probability that at least one users more careful about personal information when using wi-fi hotspot, i.e 0.979(approx).

RESULT:

<u>The result should not be impacted by this because volunteers are likely to have the most relevant responds.</u>
