Events are said to be mutually exclusive if they can not occur at the same time, that is, the probability of those events occurring at the same time is zero.
In the question given above,
P (A) = .2
P (B) = .3
P (C) = .3
P (A U B U C) = .2 + .3 + .3 = .8
Therefore, P (A U B U C) = 0.8.<span />

Answer:
24x³-62x²+49x-12
Step-by-step explanation:
We can start by multiplying the first two brackets together first.
(3x-4)(2x-1)(4x-3) = (6x²-3x-8x+4)(4x-3)
Evaluate like terms.
(6x²-3x-8x+4)(4x-3) = (6x²-11x+4)(4x-3)
Multiply the two brackets together.
(6x²-11x+4)(4x-3) = 24x³-18x²-44x²+33x+16x-12
Simplify.
24x³-18x²-44x²+33x+16x-12 = 24x³-62x²+49x-12
Tell me if you need it in factorised form.
