Jack conducted a blind taste test on some of his friends in order to determine if organic fruits tasted different than non-organic fruits. Each friend ate one type of fruit. Organic Non-organic 8 9 Apples Peaches 11 9 Blueberries 6 6 What is the probability that a randomly selected friend tasted blueberries or preferred organic? Simplify any fractions.

Respuesta :

Adding up both columns, we can conclude that Jack conducted the blind test with:

[tex]8+11+6+9+9+6=49[/tex]

49 friends.

Out of these 49 friends, 12 tasted blueberries and 25 preferred organic. This way, the probability that a randomly selected friend tasted blueberries or preferred organic is:

[tex]\frac{12+25}{49}=\frac{37}{49}\rightarrow0.76[/tex]

Or 76%
