Acertain event has only three possible outcomes.
theprobabilities of the first two outcomes are 0.3 and 0.4. what
isthe probability of the third outcome?

probability of the third outcome is 0.3

Step-by-step explanation: the summation of all possible event of a probability must be equal to 1. If two events have 0.3 and 0.4,the remaining third event is 0.3. Adding 0.3 and 0.4 and subtracting them from 1.

n=2

Step-by-step explanation:

2n+3+3n=n+11

Step 1: Simplify both sides of the equation.

2n+3+3n=n+11

(2n+3n)+(3)=n+11(Combine Like Terms)

5n+3=n+11

5n+3=n+11

Step 2: Subtract n from both sides.

5n+3−n=n+11−n

4n+3=11

Step 3: Subtract 3 from both sides.

4n+3−3=11−3

4n=8

Step 4: Divide both sides by 4.

after you do that you get the answer witch is

=2
