Aspinner 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?

Step-by-step 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 =

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

⇒

⇒

⇒

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

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400
