Probability question Watch
I don't know how to this question but I tried this way:
P(2 people have same star sign and 3 people have different)
P(3 people have same star sign and 2 people have different)
P(4 people have same star sign and 1 person is different)
P(all 5 have same star sign)
= 0.00447, the markscheme says it's 0.618, how?
because i did it so long ago, i couldn't at first remember how to do it - but this thread should help:
don't worry, there was never a question like that on my actual S1 exam!
