How do you know if a problem is extraneous or not?

Answer:

Step-by-step explanation:

An extraneous solution is a solution that's not really a solution. In other words, you work out the problem and you obtain a solution. Then you test your solution by plugging in your solution to the formula given, if the result is false then it's considered an extraneous solution.

For example, if you're solving for time it took for a football to reach the ground after somebody threw it, you would obtain two answers for time. These time answers are negative time and positive time, well the negative time makes no sense since it's before you threw the ball so we would consider that negative solution to be extraneous.

Komok [63]

Answer:

Probability of picking Red ball is 27.5%

Step-by-step explanation:

Given:

Total Number of balls = 200

Number of White balls = 100

Number of Red balls = 55

Number of Black balls = 45

We need to find the probability of the ball picked to be red.

Solution:

Now we know that;

Probability is equal to number of Possible Outcomes divide by total number of Outcomes multiplied by 100.

framing in equation form we get;

$P(Red) = \frac{\textrm{Number of Red balls}}{\textrm{Total Number of balls}} \times 100$

$P(Red) = \frac{55}{200}\times100$

$P(Red) = 27.5\%$

Hence Probability of picking Red ball is 27.5%.
