Suppose that 9 out of the 23 doctors in a small hospital are General Practitioners, 10 out of the 23 are under the age of 50, and 3 are both General Practitioners and under the age of 50. What is the probability that you are randomly assigned a General Practitioner or a doctor under the age of 50

0.6957 = 69.57% probability that you are randomly assigned a General Practitioner or a doctor under the age of 50.

Step-by-step explanation:

I am going to solve this question treating these events as Venn events.

I am going to say that:

Event A: General practitioner.

Event B: Under the age of 50.

Suppose that 9 out of the 23 doctors in a small hospital are General Practitioners

This means that

10 out of the 23 are under the age of 50

This means that

3 are both General Practitioners and under the age of 50.

This means that

What is the probability that you are randomly assigned a General Practitioner or a doctor under the age of 50?

This is:

Considering the values we have for this exercise.

0.6957 = 69.57% probability that you are randomly assigned a General Practitioner or a doctor under the age of 50.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
