So, total how many names are there in the hat ?

OpenStudy (anonymous):

I think 5

ganeshie8 (ganeshie8):

father mother 2 sister him so total = 5

ganeshie8 (ganeshie8):

so, probability for picking Darnell first time is : 1/5

ganeshie8 (ganeshie8):

probability for picking `sister` after that is : 2/4

ganeshie8 (ganeshie8):

P(Darnell AND sister) = 1/5 * 2/4 simplify

OpenStudy (anonymous):

1/10

ganeshie8 (ganeshie8):

express it as percentage

OpenStudy (anonymous):

10%

ganeshie8 (ganeshie8):

yup !

OpenStudy (anonymous):

so the first awnser is D?

ganeshie8 (ganeshie8):

thats right, see if u can try next one

OpenStudy (anonymous):

is it 16%

ganeshie8 (ganeshie8):

notice that we're replacing the names here : P(father) = 1/5 P(mother) = 1/5 So, P(father AND mother) = 1/5 * 1/5 = ?

OpenStudy (anonymous):

4%

ganeshie8 (ganeshie8):

\(\large \color{red}{\checkmark}\)

OpenStudy (anonymous):

Ok for the third one I tried and I got 16% for it

ganeshie8 (ganeshie8):

Correct !

OpenStudy (mr_perfection_xd):
