Question

The teacher of a seventh-grade class flipped a coin 100 times. The students recorded the results in the table shown below:


Side of Coin Landed On Heads Tails
Number of Flips 56 44


Which of the following best describes the experimental probability of getting heads?
The experimental probability is same as the theoretical probability.
The experimental probability is 6% lower than the theoretical probability.
The experimental probability is 6% higher than the theoretical probability.
The experimental probability cannot be concluded from the data in the table.

Answer 1

@bibby

Answer 2

what's the theoretical prob of getting heads

Answer 3

56/56?

Answer 4

they flipped a coin 100 times

Answer 5

tails: 44/44

Answer 6

oh

Answer 7

56/100

Answer 8

44/100

Answer 9

right?

Answer 10

theoretical

Answer 11

ugh wait a sec

Answer 12

in theory you will get heads 1/2 of the times you flip

Answer 13

oh 50/100?

Answer 14

yeah

Answer 15

relate the experimental and theoretical probabilities

Answer 16

ok

Answer 17

by that, I mean the experimental is either x amount bigger, x amount smaller, the same, or unknown

Answer 18

oh ok wait a sec plz

Answer 19

heads is 12% more possible than tails??

Answer 20

is that right??

Answer 21

@bibby lol r u there or whatching the movie??

Answer 22

I was tabbed out trying to cancel plans
help me decide whether or not I want to go out drinking tonight

it's snowing :(

Answer 23

oh ok lol

Answer 24

umm i dont think u should drink. its bad 4 u

Answer 25

remember that.....

Answer 26

anyhow to answer the question how much percent great than 50 is 56, we set up the equation
50x=56
x=56/50=1.12=12% more

that's really weird. that isn't one of the choices

Answer 27

I'll keep that in mind :D1

Answer 28

wow

Answer 29

so then which one do u suggest i should pick??

Answer 30

oh wait a sec..... u said to figure out how much bigger is 56 than 50... so then its 6%

Answer 31

right?

Answer 32

so then which one is it??

Answer 33

@bibby

Answer 34

it's definitely not the same, I don't want to say the experimental is 6% more, that'd be wrong

is there a way of contacting your teacher?

Answer 35

yeah but she wont help me with this question lol....... i just started a diff test.

Answer 36

module test, so she wont:( which one do u think is the closest to the answer??

Answer 37

how about d??

Answer 38

the experimental probability can be computed. we have a table
56/100 or 56% of the time it was heads

Answer 39

oh I'm stupid

Answer 40

what?

Answer 41

we're doing it out of 100 not 50. I did the thing you did last question

Answer 42

it's 6% more

Answer 43

oh ok lol thx:) got 2 more, can u help??

Answer 44

nope. B says 6% lower than theoretical

what is the experimental and theoretical philosophy

Answer 45

err probability

Answer 46

LOL

Answer 47

C?

Answer 48

thats wat i put

Answer 49

ugh nvrimd look out 4 d question :)

Answer 50

yeah it's C
