Question

what is a probability of surveying a student that is in math Spanish and chemistry round to the three decimal places

Answer 1

From the figure, the total number of students is

`\begin{gathered} N=70+3+17+15+5+60+85+5 \\ N=260 \end{gathered}`

The number 15 is common in spanish, chemistry and math.

Hence, the number of students studying spanish, chemistry and math, n=15.

Therefore, the probability of surveying a student that is in math Spanish and chemistry is,

`\begin{gathered} P=(n)/(N) \\ P=(15)/(260) \\ P=0.058 \end{gathered}`

Therefore, the
