In a survey of 100 students in an institution in Nigeria, 80 students speak

Hausa and 20 students speak Igbo.How many students speak Hausa or Igbo

anywhere from 80 to 100

To find out how many students speak Hausa or Igbo, we can use the concept of set theory and the principle of inclusion-exclusion.

First, let's establish the number of students who speak Hausa or Igbo individually. We know that 80 students speak Hausa and 20 students speak Igbo.

Next, we need to determine how many students speak both Hausa and Igbo. Since there is no information given about students who speak both languages, we assume that there is no overlap, and therefore, there are no students who speak both.

Now, we can calculate the total number of students who speak Hausa or Igbo by adding the number of students who speak Hausa and the number of students who speak Igbo.

Total = Number of students who speak Hausa + Number of students who speak Igbo
Total = 80 + 20 = 100

Therefore, all 100 students in the survey speak either Hausa or Igbo, as there is no overlap between the two groups.

To find out how many students speak Hausa or Igbo, we need to add the number of students who speak Hausa and the number of students who speak Igbo.

Given that 80 students speak Hausa and 20 students speak Igbo,

The total number of students who speak Hausa or Igbo is 80 + 20 = 100.

Therefore, 100 students speak Hausa or Igbo.
