## Howard-Wolowitz one year ago question

1. welshfella

realtive frequency of green bar = 5 / total accidents

2. Howard-Wolowitz

I did that and got A

3. Howard-Wolowitz

theres no way that right though

4. Howard-Wolowitz

would i be right for the first one with A

5. Michele_Laino

by definition, of relative frequency, we have the subsequent relative frequency for green bar: $\Large \frac{5}{{3 + 8 + 2 + 5}} = \frac{5}{{18}} \cong 0.28$ so you are right

6. Michele_Laino

similarly for red bar, we have: $\Large \frac{8}{{3 + 8 + 2 + 5}} = \frac{4}{9} \cong 0.44$
