The table below shows the students in an Algebra class.GirlsBoysTotalOwn a graphing Do not own a graphingcalculatorcalculator125176713Total181230What is the probability that a randomly chosen student will be a girl and own a graphingcalculator?

Answer 1

Step-by-step explanation:

The total number of students in the algebra class is given below as

`n(S)=30`

The number of girsl who won a graphing calculator is given below as

`\begin{gathered} n(G_h\cap G_n)=12 \\ where, \\ G_h=have\text{ }graphing\text{ }calculator \\ G_n=does\text{ }not\text{ }have\text{ }graphing \end{gathered}`

Concept:

To figure out the probabaility that a randomly chosen student will be a girl and own a graphing calculator, we will use the formula below

`Pr(G_h\cap G_n)=(n(G_h\cap G_n))/(n(S))`

By substituting the values, we will have

Hence,

The final answer is

`(2)/(5)`

The FOUTH OPTION is the correct answer
