I don't know where you're getting a power of 6 from.

Then you need

P(LMH or LHM or MLH or MHL or HLM or HML) = 6*0.5*0.35*0.15.


sorry am so thick .

if they ask for days : would that mean you do : 8 * 0.5*0.35*0.15 ?

Something missing here? But the answer will be no anyway.

Sorry , you said for 3 day you time the result by 6

would that mean for 4 days you multiply by 8 ?

how do you figure it out

thank you for your help

If there was four days, there would be 16 combinations I think.

I'm really bad at probability too so this is really helpful for me too!

Assuming you mean four days that include at least one of each then you would have various permutations of LLMH, various permutations of MMLH and various permutations of HHLM.

You need to take into account all possible combinations.
Draw a tree diagram I say, a lot easier to visualise from there. Pick out the combinations which would give one of each letter from each stem. Then do the same for the two other stem.

Drawing a tree diagram should really help you out, trust me.
