Do you know how to find the probability that the first sock is blue?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

10 socks in the drawer. 3 of them are blue. Probability = things we want / total things 3 / 10 simple.

OpenStudy (anonymous):

we put the sock back. so again there are 10 socks in the drawer. 4 are red. what's the probability we get a red sock on the next pick.

OpenStudy (anonymous):

3/25

OpenStudy (anonymous):

where do you get 3? where do you get 25?

OpenStudy (anonymous):

10 socks in the drawer. 4 are red. what's the probability we get a red sock on the next pick. you are definitely overthinking this. it's really simple. what's the probability we get a red sock on the next pick.

OpenStudy (anonymous):

red socks, 4/10

OpenStudy (anonymous):

so 3/10*4/10

OpenStudy (anonymous):

yes. ahhh i see now! you were way ahead. that simplifies to 3/25 sorry
