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

your answer is b ^w^ hope i

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
