Question

A spinner used for a game is divided into 4 sections: Yellow, Brown, Red and Orange. The spinner is spun 50 times and lands on brown 18 times. What is the experimental probability that the spinner does NOT land on brown?

Answer 1

18/50 is the likelyness that it WILL land on brown, so that means that 32/50 chance that it WONT land on brown. Simplified it would be a 16/25 chance
or if you need to write it differently a 16:9 chance with 16 as will 9 as wont

Answer 2

`(16)/(25) =0.64`

Explanation:

Given : A spinner used for a game is divided into 4 sections: Yellow, Brown, Red and Orange. The spinner is spun 50 times and lands on brown 18 times

To Find: What is the experimental probability that the spinner does NOT land on brown

Solution :

Since we are given that the spinner is spun 50 times .

Ans the spinner lands on brown 18 times

Probability of landing on brown =
`(18)/(50) =(9)/(25)`

Since we know that the sum of probabilities is 1

So, probability that the spinner does NOT land on brown is :

⇒ 1 - prob. of landing on brown

⇒
`1-(9)/(25)`

⇒
`(25-9)/(25)`

⇒
`(16)/(25)`

Thus probability that the spinner does NOT land on brown is 16/25=0.64
