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
Use Binomial Distribution, i.e,
p=0.62, q=0.38, n=4.
Required Probability
or
=1-
=1-
=1-
=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).

<u>The result should not be impacted by this because volunteers are likely to have the most relevant responds.</u>
If there are 19 red marbles in every 1 black marble, and there’s a total of 120 marbles, that means 120/19, is equal to nearly 6.3 black marbles, but since you can’t split a marble in half, it would mean that there are 6 black marbles in total. Since, 19 * 6 is 114 & there’s a remainder of 6 to approach the final answer of 120, meaning there are 6 black marbles in the bag.
Answer:
The answer is C
Step-by-step explanation:
There are 3 y's and there are three z's
3(y+z) means that you are multiplying 3 and y, and 3 and z which gives you 3y+3y
Which also equals y+y+y+3z
Answer:
$360.
Step-by-step explanation:
The interest earned on principal P, at the rate of r for the duration of t years is given by the equation I = Prt ........... (1)
Now, we have to calculate the interest earned on $3000, at the rate of 0.04 for 3 years.
Here, P = $3000, r = 0.04 and t = 3 years.
Hence, from equation (1), Interest earned, I = 3000 × 0.04 × 3 = $360 (Answer)
