40 Butterflies at Swallowtail :D
Alternate Interior angles
Answer:
B. Dependent, 1/70
Step-by-step explanation:
The probability that the first pencil is yellow is 10/50.
There are now 49 pencils, so the probability that the second pencil is blue is 7/49.
There are now 48 pencils, so the probability that the third pencil is red is 24/48.
The total probability is (10/50) (7/49) (24/48) = 1/70.
Since the pencils aren't replaced after selection, each event changes the probability of the next, so the events are dependent.
<span>It is a line that touches only one point on the circle. Not so: that's a tangent line.
It is a line that joins a point on the circle with the center of the circle. Not so: that's a radius.
It is a line that divides the circle into two equal halves. Not so; that's a diameter.
It is a line that intersects the circle at two points. True.</span>
