grandymaker [24]

Answer:

x = 12 ( two points shots )

y = 7 ( three points shots )

Step-by-step explanation:

Let´s call "x" two points shots, and "y" three points shots, then

x + y = 19

2*x + 3*y = 45

We have to solve a two-equation system for x and y

y = 19 - x

2*x + 3 * ( 19 - x ) = 45

2*x + 57 - 3*x = 45

- x = 45 - 57

-x = - 12

x = 12

And y = 19 - 12

y = 7

In a jar, there is a green, a blue, and a red marble. You draw (with replacement) a marble from the jar until you get the green

denpristay [2]

Answer:

The value is $P( X = m ) = (\frac{2}{3} )^{m-1 } * \frac{1}{3}$

Step-by-step explanation:

From question we are told that

The number of types of marbles present jar is n = 3

Generally the probability of drawing a green marble is

$P(g) = \frac{1}{3}$

Generally the probability of drawing a marble that is not green is

$P(g') = 1 - \frac{1}{3} = \frac{2}{3}$

From the question we are told that there will be continuous drawing of marbles from the jar (in such a way that after each marble is drawn it is being replaced) until a green marble drawn

Let m be the number of times marbles has been drawn when a green marble was gotten

it then means that for m - 1 times the marbles where drawn a green marble was not obtain.

Generally the probability drawing m times is mathematically is mathematically represented as

$P( X = m ) = (P(g'))^{m-1 } * P(g)$

=> $P( X = m ) = (\frac{2}{3} )^{m-1 } * \frac{1}{3}$
