Ronch [10]

Answer:

$P(GR)=\frac{2}{13}$

Step-by-step explanation:

Number Of Red Balls=6

Number Of Green Balls=4

Number Of blue Balls=3

Total Number Of Balls=6+4+3=13

Notice that the two balls are picked without replacement. In this case, the total number of balls always decreases.

P(first ball will be green and the second will be red)

$=\dfrac{4}{13} X \dfrac{6}{12} \\=\dfrac{2}{13}$

In how many ways can 2 red, 2 black, 3 white and 2 blue balls be selected from 4 red, 3 black, 4 white and 8 blue balls? In how

Montano1993 [528]

From the total pool of colored balls, one can choose 2 reds, 2 blacks, 3 whites, and 2 blues in

$\dbinom42\cdot\dbinom32\cdot\dbinom43\cdot\dbinom82=6\cdot3\cdot4\cdot28=2016$

ways.

I'm assuming no ball of the same color is distinguishable from any other ball of the same color. So when I'm considering the possible arrangements, if I had lined up the ball as

red1 - black - red2 - ...

then this would be no different that

red2 - black - red1 - ...

So I now have 9 balls to arrange, which means there are $9!=362,880$ total possible permutations of them. But order among distinct colors is assumed to not matter. This means I have to divide the total number of permutations by the number of ways I could permute balls of the same color. Then there would be a total of

$\dfrac{9!}{2!\cdot2!\cdot3!\cdot2!}=7,560$

ways of arranging the balls I had selected.

What is the approximate length of minor arc XZ rounded

allsm [11]

The length of the minor arc is 3.7 meters.

<h3>What is a minor arc?</h3>

An arc of a circle with a measurement of less than or equal to radians is referred to as a minor arc.
A minor arc's length is never greater than 180 degrees.
Arc length = 2πr(θ / 360°) where r is the radius and θ is the central angle of the arc.

Given:

radius = 3 m

central angle ∠XYZ= 70°

Now, calculate the circumference of the circle:

C = 2 π r

C = 2 × 3.14 × 3

C = 18.84 m

The circumferential length establishes a 360° central angle.

The following formula can be used to determine the minor arc's length:

Assume that the minor arc's length is XZ = x.

Now, using proportion

⇒ $\frac{18.84}{360} = \frac{x}{70}$

⇒ 18.84 × 70 = 360x

⇒ x = 1318.8 / 360

⇒ x = 3.66

⇒ x ≅ 3.7 m
