hi

do you still need help

[broken helm]

yes

[flint shore]

okay

i help

youre right

except the last one

im confused about that

how did you arrive at that

[broken helm]

it says at least 3 kings so

there can be 4 kings too

so i did 4C4 x 4C3

[flint shore]

hmm

but

there are 52 cards

and

7 cards have to be dealt

[pulsar prairie]

the solution is to add your first 2 answers together

there's no other solution

[broken helm]

can you explain why

[pulsar prairie]

i can't

[broken helm]

😭

[stray aurora]

at least three kings means either three kings or four kings

in particular, these numbers are exactly the ones you calculated previously

[flint shore]

but

wouldnt u be using binomial distribution for this

[pulsar prairie]

you wouldn't but if it was applicable it would also work like that
