You can put this solution on YOUR website! A coin is tossed with possible outcomes H or T. Then a spinner spun with possible outcomes 1 through 4;
draw a tree diagram
Root Column:: H.....T
Branch Column:: 1,2,3,4 to the right of H ; 1,2,3,4 to the right of T
-----
and list the combined outcomes
H1,H2,H3,H4,T1,T2,T3,T4
---------------------------
. What is the probability of rolling an odd number and a tail?
Pattern:: 1T and 3T
P(odd and T) = P(odd) + P(tail) - P(odd or tail) = (1/2)+(1/2)-(6/8) = 1/4
