hello??????????

Answer 8

for this... u srsly need to flip a coin 50 times and fill in the table from ur results @bubbleslove1234 ... sorry, till u do we cant help u hey

Answer 9

i have already done this

Answer 10

yeah, I don't understand how they want the statistics either for the 2, or 2 each, of cats and dogs on the chart

Answer 11

so what were ur answers for:
HH -
HT -
TH -
and
TT? -

Answer 12

hold on

Answer 13

hh=11
ht=17
th=8
tt=14

Answer 14

ok... so from ur screenshot: which question do u want to go through first?

Answer 15

the first one and work from there

Answer 16

k_ so cats are Heads, and Dogs are Tails
according to the start of ur Q: having cat or dog is 50:50 "theoretical" probability
so: Q1 - theoretical Probability of 2 cats OR 2 dogs
= P(HH) OR P(TT)
= P(HH) + P(TT)

Theoretical probability of HH =0.25
Theoretical probability of TH =0.25
Theoretical probability of HT =0.25
Theoretical probability of TT =0.25

so solve
= P(HH) + P(TT)
@bubbleslove1234 ?

Answer 17

do you know what i should get cause i am soooooooooooo confused

Answer 18

oww my brain hurts

Answer 19

Theoretical probability is:
P(HH) =0.25 (or 25%)
P(TH) =0.25 (or 25%)
P(HT) =0.25 (or 25%)
P(TT) =0.25 (or 25%)

so Q1. solve
= P(HH) + P(TT)

Answer 20

okay so 25% times 50

Answer 21

no, sorry u can either use percentages or use decimals, but u can't use both at the same time, sorry

P(HH) = 0.25
P(TT) = 0.25

so = P(HH) + P(TT) =?

Answer 22

okay

Answer 23

P(HH) = 0.25
P(TT) = 0.25

so
P(HH) + P(TT) = ?????
@bubbleslove1234 ...?

Answer 24

p(11)=0.25
p(14)=0.25

Answer 25

did you get the Question 1 answer? dog and cat?

Answer 26

nope not yet but i need fast help cause it is due today

Answer 27

no, for question 1, we only care about Theoretical results... not actual one we get from flipping a coin
so Theoretical probability of 2 heads is 25% of the time... so P(HH) = 0.25
and the Theoretical probability of 2 tails is 25% of the time... so P(TT) = 0.25

so whats .25 + .25 ?

Answer 28

50

Answer 29

perfect. PHH + PTT = 0.50 .... or 50 %
so Q1
= 50% chance

Answer 30

oh so is that the answer

Answer 31

Q1. chance family has 2 cats or 2 dogs?
= P(CC) or P(DD)
= 0.5 .... or 50%
yep, answer

Answer 32

for the first one

Answer 33

Q2.
how does 2 coins simulate which 2 pets a family has?
answer: 50% chance of choosing a cat or a dog, and they chose twice
(50% either cat or dog, then 50% chance either cat or dog for the 2nd pet also)

so exactly as flipping a coin... twice
(50% either heads or tail, then 50% chance either head or tail on the 2nd toss also)

Answer 34

Q3.check if this is correct:
ur results were:
