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:
a=50
b=40
c=80?
Step-by-step explanation:
a=50 (180-130)
b: 50+90=140 180-140= 40 b=40
c= 40+60=100 180-100=80?
Answer:
300
Step-by-step explanation:
If you would like to solve the system of equations, you can do this using the following steps:
y = - 3
y = x - 0.8
_________
y = y
- 3 = x - 0.8
x = - 3 + 0.8
x = - 2.2
(x, y) = (- 2.2, - 3)
The correct result would be <span>(- 2.2, - 3).</span>
