add all numbers and divide by the count of numbers.
This relative frequency is an experimental probability: that of getting a red on a spinner. In 300 spins, we'd expect to get 0.4(300), or 120, reds.
Answer:
1/8
Step-by-step explanation:
P(5) = 1/8
-----------
Since the circle is centered at the origin, we can use the equations
x² + y² = r²
x = r cos θ
y = r sin θ
We know y = 8 and r = 10. Solving for x
x² + 8² = 10²
x = 6
From this equation:
x = r cos θ
6 = 10 cos θ
cos θ = 6/10 = 0.6

(The same elements are written once.)
b:A u C

c:B u C

Note:I used dots to mean commas .
Good work!
