Check the picture below.
if we know the endpoints of the circle, then its center must be the midpoint of those two endpoints.
I️ swear I️ knew how to do this
Answer:
area of one of the basses is 1.44 square feet
area of each lateral rectangular face is 0.96 square feet
SURFACE AREA OF THE PAPERWEIGHT IS 6.72 square feet.
Step-by-step explanation:
Problem 3
Disjoint events are two (or more) events that cannot happen at the same time. An example would be flipping heads and tails at the same time with the same coin. Another example is selecting an ace of spades and selecting an ace of diamonds, when you only select one card.
In general notation, P(A and B) = 0 if and only if A and B are disjoint.
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.3 + 0.1 - 0
<h3>P(A or B) = 0.4</h3>
=========================================
Problem 5
Same idea, but different numbers
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 1/3 + 1/4 - 0
P(A or B) = 4/12 + 3/12 - 0
<h3>P(A or B) = 7/12</h3>
