Howwwwww?????

[flat osprey]

I suggest watching bicens video on “experiments with multiple trials”

[lethal grove]

jus use he casio fx calc its much more ezier

[flat osprey]

But he won’t understand why

[lethal grove]

U dont need to knw why lool

[flat osprey]

Bruh it’s better to understand why

[strange bloom]

i understand what you mean

but try plug in diff numbers in the choose function

from 0-20

you’ll see the highest probability you’ll get is the one with 20 choose 10

i’m guessing that’s what the mark scheme is trying to say

??

Out of the 20 throws the number of successes (landing a head) is 10

20C10 is the possible ways of winning and 0.5 is the probability of landing a head

It would actually be 20C10 * (0.5)^10 * (0.5)^10 but since the probability of landing a head and tails is the same you can combine them to get (0.5)^20

Lmk if you don’t get any of it

Did you watch that video?

[strange bloom]

he understands the maths behind it

he doesnt get the statement they wrote at the bottom

which is what i said

he's basically explaining this part

where the 0.5 to the power of 20 comes from

[strange bloom]

getting 10 heads is more likely than getting any other number of heads
