The table below shows which hand is favored by each person from a sample of 100 people (50 male and 50 female). Use the informat
Yuliya22 [10]

The probability that a randomly selected person from the sample will be female or left-handed will be 0.05.

<h3 /><h3>What is the probability?</h3>

Probability is synonymous with possibility. It is concerned with the occurrence of a random event.

Probability can only have a value between 0 and 1. Its simple notion is that something is very likely to occur. It is the proportion of favorable events to the total number of events.

Given data;

Total number of sample,n(S) = 100 person

No of female or left-handed is,n(E) =5

P(E) is the probability that a randomly selected person from the sample will be female or left-handed

The probability that a randomly selected person from the sample will be female or left-handed is found as;

P(E) = n(E)/n(S)

P(E) = 5 / 100

P(E) = 0.05

Hence the probability that a randomly selected person from the sample will be female or left-handed will be 0.05.

I have a really hard time with math. Please explain this to me.
Igoryamba
F(x) = x2-3 The domain of a polynomial is all x: (-∞,∞)Since f(x) is a quadratic equation, its graph is a parabola.  Since the coefficient of the x2 term is positive (1), the graph opens upward and the vertex is at the bottom and is the lowest or minimum point of f(x).  The vertex is located at the point (0,-3).  Hence the range is from -3 to infinity: [-3,∞)
