Answer:

A. 12

Step-by-step explanation:

Let the number be A

8 x (A - 6) = 4 x A

Expand the left side

8 x A - 8 x 6 = 4A

8A - 48 = 4A

Add 48 to both sides

8A - 48 + 48 = 4A + 48

8A = 4A + 48

Subtract 4A from both sides

8A - 4A = 4A - 4A + 48

4A = 48

Divide both sides by 4

A = 48/4

A = 12

If there are 17 green marbles in a jar of 65 marbles, what is the probability of drawing 2 green marbles at random without repla

erastovalidia [21]

Answer:

Option b) $\frac{17}{260}$

Step-by-step explanation:

We are given the following information in the question:

Total number of marbles = 65

Number of green marbles = 17

We have to find the probability of drawing 2 green marbles at random without replacement.

Formula:

$Probability = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

$\text{P(Drawing 2 green marbles at random without replacement)} = \\\text{Probability of drawing }1^{st} \text{ green marble}\times \text{Probability of drawing }2^{nd} \text{ green marble}$

$\text{Probability of drawing }1^{st} \text{ green marble} = \displaystyle\frac{17}{65}\\\\\text{Probability of drawing }2^{nd} \text{ green marble} = \displaystyle\frac{16}{64}$
