how many females have blue eyes

[pulsar cosmos]

19

[verbal dragon]

ok and males?

[pulsar cosmos]

40

[verbal dragon]

no

isnt it 0.6 of 80

[verbal dragon]

?

[pulsar cosmos]

I ment 48

[verbal dragon]

ok

so 48 + 19 people have blue eyes

or 67

if the probability is 50% then 1/2 have blue eyes

[verbal dragon]

so what is 1/2 of 130

[pulsar cosmos]

65

BTW we're u get 130

[verbal dragon]

50 + 80

total amount of people

so if we have 67/130 and 50% = 65/130 are we greater than 50%?

[pulsar cosmos]

Oh okay

[sleek crypt]

ring, when ever u have troubles with probability, try making a tree diagram

[pulsar cosmos]

What that

It in the middle so no

I think

Wait yes

[sleek crypt]

Put the probabilities on each edge

[pulsar cosmos]

Oh one of them

[sleek crypt]

no no, there are 4 edges, put the probabilities on them

given a person, what are the chances of it being male? and female?
