Determining the Probability of Choosing a Female or Right-Handed Student

What is the probability of choosing a female or right handed student?

To determine the probability of choosing a female or right-handed student, we’ll need some additional information such as the total number of students and the number of females and right-handed students

To determine the probability of choosing a female or right-handed student, we’ll need some additional information such as the total number of students and the number of females and right-handed students.

Let’s assume we have the following information:

– Total number of students: 100
– Number of females: 60
– Number of right-handed students: 70

To find the probability, we need to calculate the number of favorable outcomes (choosing a female or a right-handed student) and divide it by the total number of possible outcomes.

Step 1: Calculate the number of favorable outcomes (female or right-handed student):
– To find the number of females or right-handed students, we should add the number of females and the number of right-handed students. However, since some students might be both female and right-handed, we need to subtract the number of students who are both.

Number of females or right-handed students = Number of females + Number of right-handed students – Number of students who are both

Number of females or right-handed students = 60 + 70 – (number of students who are both)

Let’s assume there are 30 students who are both female and right-handed. We can substitute this value into the equation:

Number of females or right-handed students = 60 + 70 – 30 = 100

Step 2: Calculate the total number of possible outcomes (total number of students):
– In this case, the total number of possible outcomes is simply the total number of students, which is 100.

Step 3: Calculate the probability:
– The probability is given by the number of favorable outcomes divided by the total number of possible outcomes.

Probability = Number of favorable outcomes / Total number of possible outcomes

Probability = 100 / 100 = 1

So, the probability of choosing a female or right-handed student is 1. This means that it is certain that you will choose a female or right-handed student when selecting from this group of students.
