Is Event B dependent or independent of Event A? A: A green ball is drawn from a box with five balls and placed next to the box.
Zarrin [17]

Answer:

Step-by-step explanation:

Given that events are as follows:

A: A green ball is drawn from a box with five balls and placed next to the box. B: A red ball is drawn next and placed next to the green one

i.e. drawings of balls are made without replacement

Suppose there are m green balls and n red balls, where m+n =5

Prob of drawing green ball =m/5

After I draw made remaining are n red balls and m-1 green balls

Prob of drawing red ball now =n/4

Prob for drawing one green and one red simultaneously = \frac{mC1*nC1}{5C2} \\= \frac{mn}{10}

Product of the two probabilities = \frac{m}{5} *\frac{n}{4} \\=\frac{mn}{20}

Michael goes through the same traffic light each day on his way home from work. This year, the traffic light has been green 28 t
ASHA 777 [7]

Answer:

y = 12

Step-by-step explanation:

Given

Green = 28

Red = 35

Yellow = y

Prediction of yellow = 16 of 100

Required

Determine y

First, we need to calculate the probability of yellow.

Probability of yellow =

Probability = Yellow/Total

Where

Total = Yellow + Red + Green

Total = y + 35 + 28

Total = y + 63

So,

Probability = y/(y + 63)

Also, the prediction of yellow is 16 out of 100.

Represent this as probability.

Probability = 16/100

Equate both expressions to solve for y

y/(y + 63) = 16/100

y/(y + 63) = 0.16

Multiply both sides by (y + 63)

y = 0.16(y + 63(

y = 0.16y + 10.08

Collect like terms

y - 0.16y = 10.08

0.84y = 10.08

Solve for y

y = 10.08/0.84

y = 12

A square patio has an area of 170 square feet. How long is each side of the patio to the nearest tenth?
Pavlova-9 [17]
Since we know that squares have the same length on all sides, you would find the square root of 170
√170=13.03840481
rounded to the nearest tenth would be 13.1

You can check your work by multiplying 13.1 by 13.1 which equals 170.3

I try to explain the problem and give the answer, I hope this helps!
