Question

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.

Answer 1

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

`8+11+6+9+9+6=49`

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:

`(12+25)/(49)=(37)/(49)\rightarrow0.76`

Or 76%
