Question

in a class of 12 students 5 are boys and rest are girls find the probability that a student selected will be a girl

Answer 1

Answer:

the answer is 7/12 or say 0.58

Step-by-step explanation:

In a class of 12 students if 5 boys are there then there should be 12-5 number of girls which is 7

Hence, the P(a student selected will be a girl) = 7/12 = 0.58

                                                                           

Answer 2

The required probability is $\dfrac{7}{12}$

Step-by-step explanation:

Since we have given that

Number of students = 12

Number of boys = 5

Number of girls = 7

So, probability that a student will be a girl would be

$\dfrac{\text{Number of girls }}{\text{Number of students}}\\\\=\dfrac{7}{12}$

Hence, the required probability is $\dfrac{7}{12}$
