Question

1.From a barrel of colored marbles you randomly select randomly select 6 blue, 4 yellow, 2 red, 3 green and 5 purple. Find the experimental probablilty of randomly selecting a marble that is not yellow.

2/9
4/5
2/3
10/19


2.Sally works in a afactory that produces 1,000 television each day. When 40 televsion were sampled it was found that 6 were defective estimate how many defective televisions are made each day.

17
152
196
248

3.If a coin is tossed and a number cube is rolled what is the probability that the coin shows heads and the number cube shows 3.

1/2
1/9
1/6
1/12

Answer 1

Answer:

Number 1 is 4/5

Step-by-step explanation:

So first you add all of them together.4+2+3+5=20

Then subtract 4 since there is 4 that are yellow.4-20=16.

Then divide 20 by 2 and 16 by 2.20/2=10,16/2=8.

Then divide them by 2 again.10/2=5,8/2=4.

Now that you can't reduce them anymore just determine which is the numerator.

16/20=8/10=4/5

Solution:4/5

Hope this helps

Answer 2

1. The experimental probability of randomly selecting a marble that is not yellow = 4/5.

2. 150  defective televisions are made each day..

3. probability coin shows heads and the number cube shows 3 is 1/12

What is Probability?

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.

Given that:  6 blue, 4 yellow, 2 red, 3 green and 5 purple.

probability of randomly selecting a marble that is not yellow is

= 6+2+3+5 (exclude yellow)/ 6+4+2+3+5

= 16/20

=4/5.

2. When 40 television were sampled it was found that 6 were defective

then, Probability of 6 out of 40 = 4/40= 0.15

= 0.15 * 1000 = 150

Hence, 150 defective televisions are made each day.

3. .If a coin is tossed and a number cube is rolled

probability coin shows heads and the number cube shows 3.

= 1/2 (Probability of head) * 1/6 (probability of number cube shows 3)

= 1/12
