Question

Given the set of all even integers between and including -18 to -6 , what is the probability of choosing a multiple of -6 from this set?1/93/74/9

Answer 1

TheseGiven the set: {-18, -16, -14, -12, -10, -8, -6}

This is 7 numbers

Multiplies of -6 are:

`\begin{gathered} -6*1=-6 \\ -6*2=-12 \\ -6*3=-18 \end{gathered}`

This is 3 numbers

Therefore, the probability is given by:

`P=\frac{multiplies\text{ of }-6}{total\text{ set }}`

So:

`P=(3)/(7)`

Answer: 3/7
