"Tossing a die" is assumed to mean choosing a random face of a cube with faces numbered 1 through 6 such that the probability of choosing any particular face (number) is 1/6.

Event a is "observe a 2". Event b is "observe an even number". The event "a and b" is "observe 2 and an even number". This matches precisely the description for event a. In other words

... a and b = a

... p(a and b) = p(a) = p(choosing 2) = 1/6

Answer:

Option- B

An experiment involves tossing a die. these are some of the events during which we can be able to observe an even number.

Step-by-step explanation:

It is more obviously to know that there will be six sides for us to observe and each time we will get an even number to observe during the process.So, it all goes with the mechanisms of the probability that are taken under considerations when we speak about such events to happen.

Please answer!!!! please!!!!!!

The problem here is: Too many words.

If you boil the problem down to the bare facts, the question is:

   "$210 is 15% of what number ?"

I'm pretty sure you can take it from there,
but here's the rest of it anyway:

$210 = 15% of (March amount)

      $210 = 0.15 x (March amount)

Divide each side by 0.15 :   $1400 = March amount .

Check:
1400 + 210 = 1610
1.15 x 1400 = 1610 yay!

ANSWER ASAP!!!! PLEASE INCLUDE STEP BY STEP EXPLANATION DO A.

Answer:

Step-by-step explanation:

I prefer the equation in this format

$\frac{3 |m - 2 {n}^{2} | }{4}$

substitute -4 for m and 6 for n

$\frac{3 | - 4 - 2( {6}^{2}) | }{4}$

square the 6 then multiply by 2

$\frac{3 | - 4 - 72| }{4}$

solve inside the absolute value then multiply by 3

$\frac{3 | - 76| }{4}$

$\frac{228}{4}$

divide by 4

400$ is fivided between kas, jaspar, and jae so that kas has twice as much as jaspar and jaspar has three times as much as jae.

Fynjy0 [20]

Let jae have x dollars. Thus, we can make the equation:-

x + 3x + 2*(3x) = 400

4x + 6x = 400

10x = 400

x = 40

So jae has $40 and

jaspar has 3x = 3* 40

= $120 dollars (answer

What is the equation of the blue line?

sergejj [24]

Answer:

• From the general equation of a line:

${ \rm{y = mx + b}} \\$

m is slope
b is y-intercept.

→ Consider points (4, 4) and (2, 3)

${ \rm{slope = \frac{y _{2} - y _{1} }{x _{2} - x _{1} } }} \\ \\ { \rm{m = \frac{3 - 4}{2 - 4} = \frac{ - 1}{ - 2} }} \\ \\ { \underline{ \rm{ \: \: m = \frac{1}{2} \: \: }}}$

→ find the y-intercept:

${ \rm{y = mx + b}} \\ { \rm{3 = ( \frac{1}{2} \times 2) + b}} \\ \\ { \rm{3 = 1 + b}} \\ \\ { \underline{ \rm{ \: \: b = 2 \: \: }}}$

• Therefore, equation of a blue line is

${ \boxed{ \rm{y = \frac{1}{2}x + 2 }}} \\$
