Binomial distribution

[night moth]

Please help.

[iron bolt]

=1 is the sum of the formula where x changes from 1 till it reaches n, just use ur calculator for binomial cd (cumulative)

[night moth]

So I just keep inputting values until I get a probability >0.95

[iron bolt]

Send the whole question

[iron bolt]

P(x>=1) = 1 - p(x=0)

[night moth]

Hm k

Where does that come into the forumla

[iron bolt]

Ur basically looking for when p(x=0) < 0.05

Nc0 is always 1

P^0 = 1

(1-p) ^ n < 0.05 is what ur looking at here I believe

1-p is 0.95 so it's (0.95)^n < 0.05

U can use logs to find what n has to be when it = 0.05 and just round up and you'll get ur answer

Tyyy

We haven’t even gotten onto logs yet so this question is weird
