Question 11 (Multiple Choice Worth 1 points)

(06.05 HC)

Two groups separately performed an experiment by tossing a coin in the air. Group A performed 50 trials and group B performed 100 trials. Each group recorded the results in the table below:


Group Heads Tails
A 30 20
B 52 48


What conclusion can be drawn about the number of trials and the probability of the coin landing on heads or tails?

Answer 1

The experimental probability and the theoretical probability for group A is same.
The experimental probability and the theoretical probability for group B is same.
The experimental probability is closer to the theoretical probability for group B than group A.
The experimental probability is closer to the theoretical probability for group A than group B.

Answer 8

the "experimental probability" is from the numbers in your table.
the theoretical probability is from "theory"

any idea what the theoretical probability is to get "heads" when you flip a coin ?

Answer 9

i have no idea @phi

Answer 10

if you flip a coin lots of times, do you expect to get:
1) more heads than tails
or
2) more tails than heads
any idea?

Answer 11

nope

Answer 12

what's the theoretical prob of 50 coin tosses?

Answer 13

landing heads I mean

Answer 14

30?

Answer 15

no 25/25
