A bag contains coloured balls. A ball is taken at random from the bag, its colour is noted, and the ball is replaced.
A second ball is taken at random from the bag, its colour is noted, and the ball is
replaced.
The probability that the ball is red is 0.2.

Work out the probability that only one of the two balls taken is red.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12

c(x)= 6x + 3
