Alinn flipped a coin 20 times. The coin landed heads up 12 times and tails up 8 times. Part A: Based on the results, what is the experimental probability of the coin landing heads
up? Show your work. (5 points)
Part B: What is the theoretical probability of the coin landing heads up? Show your work. (5
points)

0.6

Step-by-step explanation:

A: when a coin is thrown and it lands,it either lands head up or tail up..now there is every possibility it lands head

the question said it landed 12 times heads up

and it was thrown 20 times

12÷20

=for every 5 throws there is probability of getting 3 heads up

B: 12÷20

6÷10

=3÷5

=0.6

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
