At a hot air balloon festival, Natalie made note of how many passengers were in each balloon and the color of each balloon. 1 passenger 2 passengers Blue 11 19 Yellow 0 22 Green 22 3 Orange 4 13 What is the probability that a randomly selected hot air balloon contains 2 passengers or is not green? Simplify any fractions.

Respuesta :

We will have the following:

*The probability of a selected air ballooncontaining 2 passengers:

[tex]p=\frac{19+22+13}{19+22+3+13+11+0+22+4}\Rightarrow p=\frac{27}{47}\Rightarrow p=0.5744680851\ldots[/tex]

So, the probability of the air balloon containing 2 or not being green is approximately 57%.
