so each dice has numbers
1,2,3,4,5,6
the eve numbers are
2,4,6
odd are others
1,3,5
so 1/2 are odd
therefor 1/2 of 60 is how many times it would get even
1/2 of 60=1/2 times 60=30
No not good predicition
my prediction would be 30 tiemes
Your Question:
John is about to roll a six-sided, fair number cube 60 times. He wants to predict how many times the cube will land on an even number. He makes a prediction of 20 times. Is it a good prediction? What would your prediction be based on theoretical probability?
My answer:
each dice has these 6 numbers
1,2,3,4,5,6
the even out of all of the numbers are
2,4,6
The others are odd (obviously)
1,3,5
So 1/2 are odd.
1/2 of 60 is the number of times it would get even numbers,
1/2 of 60=1/2 times 60=30
My prediction was 30!

Par b) Explain how you find the area of the shaded region. What was your thought process?
Answers
Area of rectangle = length*width
Area of circle = (π/4)*diameter²
b) The figure shows the width of the rectangle is 14 ft, the same as the diameter of the circle. The length of the rectangle is shows as 21 ft. The shaded area is the difference ...
Shaded Area = Area of rectangle - Area of circle
Shaded Area = (21 ft)*(14 ft) - (π/4)*(14 ft)²
Evaluating this expression, we have
Shaded Area ≈ 294 ft² - 153.9 ft² = 140.1 ft²
