Stats help please!

Hey, I'm stuck on this really simple question and I just can't work out what I'm doing wrong :frown:

A dance club has these members:
Adult male: 6
Child male: 5
Adult female: 4
Child female: 10

Two members are chosen at random. Find the probability that one of these members is a female child and the other is an adult male.

I've tried 16/25, 12/125, 1/10 but none of these is right... what should I be doing?

Thanks :smile:

1/10 is close. How did you get that?

(10x6)/(24x25)

(10x6)/(24x25)


And in words, do you know what this represents in terms of who you pick first and second?

Ohhh it's the probability of picking female child then adult male, so I need to multiply it by 2 to find female child/adult male OR adult male/female child (either order) ? Which gives 1/5 which is the right answer! Thank you :smile:
