Question 3 Your roll a red number cube and a purple number cube at the same time.
Calculate P(
AB)
Event A is the probability of roling doubles.
A={(1,1),(2,2),(3,3),(4,4),(5,5),(6 ,6)}
Event B is the probability of rolling two odd numbers.
B = {(1,1),(1,3),(1,5),(3,1),(3,3),(3,5 ),(5,1),(5,3),(5,5)}

a² + b²= c²

24² + 7² = c²

c= 25

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
