Question

help with couple of probability questions

Answer 1

@Jack1

Answer 2

yo... well a certain event... probability would be 100%, yeah?
and an impossible event... probability would be 0%, so can't happen

Answer 3

zat make sense for Q1?

Answer 4

yes

Answer 5

cool, so q2
how many realistic possible outcomes if u flip a coin once?

Answer 6

heads or tails

Answer 7

for 2 i say 100

Answer 8

rightt?

Answer 9

yep, so 2 possible outcomes, and unless its a weighted or double sided coin, it's a 50 50 chance, so 50% change of landing heads and 50% chance of landing tails

Answer 10

so for 2 it is 100 cause it is 50 50 correct?

Answer 11

exactly = 100 for Q2, perfect.
50% x 200 = 0.5 x 200 = 100

Answer 12

how about 3?

Answer 13

experimental vs theoretical... yep
so the experimental probability is the one you (like srsly u) get if u were to do the experiment
so if u experiment and only flip a coin 10 times, and it comes down heads 7 times and tails 3 times... your experimental probability for heads is 7/10 = 0.7 = 70%

Answer 14

ok yeah that is what i was think

Answer 15

last one

Answer 16

but u know for a coin, the theoretical probability is 50% heads... so if u kept flipping it like 100 times, you'd get closer and closer to the theoretical prob, yeah?

Answer 17

yeah

Answer 18

4. well, it's a standard coin... because it doesn't say that it's not, so regardless of the outcome of the last 200 or 1 million flips, the probability of heads is still 50% every time the coin's flipped

Answer 19

thxs

Answer 20

np man ;)
