An aleatory experience consists of turning an arrow on a roulette two times. (3 triangles, 1 circle, and two hexagon)
Question : What is the probability of obtaining exactly one haxagon.
]]>but i still don't understand the logic behind it how did you get those numbers ?ty
]]>oh = ( 4 / 6 ) ( 2 / 6 )
ho = ( 2 / 6 ) ( 4 / 6 )
oo = who cares
hh = who cares
Can you finish that?
]]>explain this
oh
ho
oo
hh
Let me show you how to draw the tree without drawing it:
This is your set of possibilities,
now the triangles and the circle we are not interested in so we give them the generic label of "other." Your set becomes,
the tree looks like this,
oh
ho
oo
hh
do you follow?
