What is the probability of rolling a four then a three

spayn [35]

Answer:

$\frac{1}{36}$

Step-by-step explanation:

Total possibilities when we a roll a die at a time are 6

given we should have four for first time and then three

let us assume we rolled the dice we may get 1,2,3,4,5,6(any of these) the probability to get 4 is

PROBABILITY= $\frac{\textrm{FAVOURABLE CHANCES}}{\textrm{TOTAL CHANCES}}$

Favourable chances=1

Total chances=6

Probability= $\frac{1}{6}$

the prabability to get 4 in first roll is $\frac{1}{6}$ .

let us assume we rolled the dice for second time again we may get 1,2,3,4,5,6(any of these) the probability to get 3 is

Favourable chances=1

total chances=6

probability= $\frac{1}{6}$

the probability to get 3 in second roll irrespective of first one is $\frac{1}{6}$

the probability to get 4 in first time and then 3 is

The probability to occur both events at a time is multiplication of individual probabilities

So,

probablility to get 4 in first roll= $\frac{1}{6}$

probability to get 3 in second roll= $\frac{1}{6}$

probability to occur both at a same time is = $\frac{1}{6}$ $\times$ $\frac{1}{6}$ = $\frac{1}{36}$

Find the equation of the straight line passing through the points (4; 2) and (2; 4).

Alecsey [184]

Use point-slope form.

But first let's find the slope.

(4, 2), (2, 4)

m = y2-y1/x2-x1

m = (4 - 2)/(2 - 4)

m = 2/-2

m = -1

So this is the slope, now we can plug this into the equation along with any point.

y - y1 = m(x - x1)

Where y1 is the y-value of the point, x1 is the x-value, and 'm' is the slope.

Let's plug in point (4, 2):

y - 2 = -1(x - 4)

This can be one of your options.

Distribute -1:

y - 2 = -x + 4

Add 2 to both sides:

y = -x + 6

This can be another of your options.

Add 'x' to both sides:

x + y = 6

This can be another of your options.
