Answer:

Therefore the probability that the card is not brown is \frac12.

Step-by-step explanation:

Probability: Probability is the ratio of the favorable outcome to the total outcome.

Probability =\frac{\textrm{Favorable outcome}}{\textrm {Total outcome}}

Given that, a box contains  2 cards blue in color , 4 cards brown in color and 6 cards yellow in color.

Total number of cards= (2+4+6)=12

∴P(getting a brown card)

=\frac{\textrm{No. of brown card}}{\textrm{Total no. of card}}

=\frac{6}{12}

=\frac12

∴P(not getting a brown card)

=1 - P(getting a brown card)

=1-\frac12

=\frac12

Therefore the probability that the card is not brown is \frac12.

Answer:

2/3

Step-by-step explanation:

hey there!

so our first step is to find the total number of cards

2+4+6=12

now we have to find the number of cards that are not brown

2+6=8

the probability would be 8/12

this can be simplified to 2/3 by dividing the numerator and denominator by 4

2/3 is also equal to 66.67%

Sladkaya [172]

Answer:

The time it took until 2 inches of rain fell is 8 hours

Step-by-step explanation:

You know that the proportional relationship between the amount of time (in hours) it had been raining, x, and the amount of rain (in inches) it had fallen, y, is y = 0.25*x

To find the time that passed until 2 inches of rain fell, you must replace the amount of rain (in inches) that had fallen "and" by that value. In this way the following expression is obtained:

2= 0.25*x

Solving:

\frac{2}{0.25}=x

8 = x

So, remembering that the amount of time it had been raining, x, is expressed in hours, <u><em>the time it took until 2 inches of rain fell is 8 hours</em></u>.

Make them all fractions over 4, so 3 would be 12/4, and 1 1/4 would be 5/4 so add them together 
12/4+5/4= 17/4 then divide by 4 to reduce it, to get 4 1/4

The probability of hitting the black circle is closer to 0 than it is to 1. because: find area of circle ~ 3.14*r^2
which is 3.14 because the radius squared is 1. so 1*3.14= 3.14
 and the area of the whiteness is 121.
subtract 3.14 from 121 and you get 117.86 
this answer is closer to a 0 probability than the white space. the white space is closer to a probability of 1.

Answer: Yes

Step-by-step explanation:

From the question, we are informed that a survey was conducted of 880 college students attending the same university and that they were offered a list of 10 different internet service providers and were asked to select the one they prefer.

Basee on this information, if everyone selected equal numbers, each service provider will get (880 / 10 = 88 students).
