The numbers that are divisible by 3 are:

3, 6, 9, 12, 15, 18, 21, 24
that is 8 numbers divisible by 3

24-8=16 numbers NOT divisible by 3

so the probability of not picking a number divisible by 3 is 16/24

hope this helps and is right :)

Suppose an opaque jar contains 3 red marbles and 10 green marbles. The following exercise refers to the experiment of picking tw

kow [346]

Answer:

$\frac{5}{13}$

Step-by-step explanation:

Given,

Red marbles = 3,

Green marbles = 10,

So, the total marbles = 3 + 10 = 13,

$\because \text{Probability}=\frac{\text{Favourable outcomes}}{\text{Total outcomes}}$

Since, here replacement is not allowed,

Thus, the probability of getting a green marble and a red marble

= first red and second green + first green second red

$=\frac{3}{13}\times \frac{10}{12}+\frac{10}{13}\times \frac{3}{12}$

$=2\times \frac{3}{13}\times \frac{10}{12}$

$=\frac{30}{78}$

$=\frac{5}{13}$

Note : The probability of getting a green marble first and a red marble second

= $\frac{10}{13}\times \frac{3}{12}$

$=\frac{30}{156}$

$=\frac{5}{26}$

(x - 2)² + 6x – 7 Which of the following is equivalent to

podryga [215]

Answer:

$x^2 +2x-3$

Step-by-step explanation:

Given

$(x - 2)\² + 6x - 7$

Required

The equivalent

We have:

$(x - 2)\² + 6x - 7$

Expand

$(x - 2)\² + 6x - 7 = x^2 -2x-2x +4 +6x - 7$

Collect like terms

$(x - 2)\² + 6x - 7 = x^2 -2x-2x+6x +4 - 7$

$(x - 2)\² + 6x - 7 = x^2 +2x-3$

Hence, the equivalent is:

$x^2 +2x-3$
