Probability is simply how likely something is to happen.
Whenever we’re unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.
The best example for understanding probability is flipping a coin:
There are two possible outcomes—heads or tails.
What’s the probability of the coin landing on Heads? We can find out using the equation P(H) = ?P(H)=?P, left parenthesis, H, right parenthesis, equals, question mark.You might intuitively know that the likelihood is half/half, or 50%.
Tips
The probability of an event can only be between 0 and 1 and can also be written as a percentage.
Answer:
3
Step-by-step explanation:
Find 'c' first by using the Altitutude Rule:
4/c = c/9
cross-multiply to get:
c = 
or 6
Now you can find 'a' by using the Pythagorean Theorem:
4² + 6² = a²
a = 
Now you can find 'b' by using the Pythagorean Theorem:
()² + b² = (9+4)²
52 + b² = 169
b² = 
b = = 
b = 3
Answer:
-2
Step-by-step explanation:
2(x+3)=2
Divide both sides by 2:
x+3=1
Subtract 3 from both sides:
x=-2
Hope this helps!
