2: A bag contains 5 black counters, 4 blue counters, and

drek231 [11]

Answer:

The probability that the counter was blue is $\mathbf{\frac{2}{5}}$

Step-by-step explanation:

Number of black Counters = 5

Number of blue Counters = 4

Number of white Counters = 1

We need to write down the probability that the counter was blue.

First find Total Counters

Total Counters = Number of black Counters + Number of blue Counters + Number of white Counters

Total Counters = 5+4+1

Total Counters = 10

Now, we need to find probability that the counter taken was blue

The formula used is:

$Probability= \frac{Number\:of\:favourable\:outcomes}{Total\:outcomes}$

There are 4 blue counters in the back, so Favourable outcomes = 4

$Probability= \frac{Number\:of\:favourable\:outcomes}{Total\:outcomes}\\Probability= \frac{4}{10}\\Probability= \frac{2}{5}$

The probability that the counter was blue is $\mathbf{\frac{2}{5}}$

Give an example of a rational function that has a horizontal asymptote at y = 0 and a vertical asymptote at

Vesnalui [34]

F(x)=x^2/(x-2)(x-1), the degree of the numerator and the degree of the denominator equal and the quotient of their coefficient equal to 1(horizontal asymptote means that the lines approach a certain number when the input approaches positive or negative infinity)
and when plugging in 2 or 1 as input, the output is undefined.
