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 />
if correct mark me as brainiest
Answer:
okay nice to know sir.
Step-by-step explanation:
5-x÷3=-7
Add 3 to both sides of the equation.
5x=3+7
Divide each term by 5 and simplify.
Divide each term in 5x=10 by 5
5x/5=10/5
Reduce the expression by cancelling the common factors.
x= 10/5
Divide 10 by 5
Answer <em>x </em>=2
