Question

3) In Saraswati Vidyalaya, out of total 72 students in a class, 8 students are coming to school by Bicycle. If one student is selected at random, then to find the probability that he is coming to school by Bicycle, complete the

following activity​

Answer 1

$\underline{\underline{\Large{\sf{Given : }}}}$

• Total number of students in Saraswati Vidyalaya = 72 students
• Number of students coming to school by Bicycle = 8 students

$\underline{\underline{\Large{\sf{To \: calculate : }}}}$

• The probability that he is coming to school by bicycle.

$\underline{\underline{\Large{\sf{Calculations : }}}}$

Here, it's given that total number of students is 72 students and out of 72 students, 8 students are coming to school by the means of bicycle. And we need to find the probability that he is coming to school by Bicycle.

★ Number of students coming to school by Bicycle out of 72 students :

$\longrightarrow$ 8 students

$\purple{\dag}$ In fraction :

$\longrightarrow$ $\rm{\dfrac{No. \: of \: students \: coming \: by \: Bicycle}{Total \: no. \: of \: students}}$

$\longrightarrow$ $\rm{ \pmb{ \purple{\dfrac{8}{72}}}}$

According to the Question,

Now, we will convert $\dfrac{8}{72}$ into it's simplest form,

$: \implies \sf \: \cancel\dfrac{8}{72}$

On simplifying,

$: \implies{ \underline{\boxed {\red{\sf Probability = \rm\pmb{\dfrac{1}{9}}}}}} \: \pink{ \bigstar}$

Therefore, the probability that he is coming to school by Bicycle is 1/9.
