1 answer:
Answer:
66.7%
Step-by-step explanation:
Please find attached the complete question
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
probability that a randomly selected point within the circle falls in the white area = degree occupied by white area / sum of angles in a circle
sum of angles in a circle = 360
degree occupied by white area = sum of angles in a circle - sum of degrees of shaded area
360 - (60 + 60) = 240
240 / 360
convert to its simplest form by dividing by 120 = 2/3
2/3 x 100 = 66.7%
