The probability of a dry day is 1/8 If it is a dry day, the probability that Blake cycles to work is 5/14 that he drives to work is 5/14
and that he takes the train to work is 2/7
If it is a wet day, the probability that Blake cycles to work is 3/16 that he drives to work is 1/4 and that he takes the train to work is 9/16

Determine the probability that Blake takes the train to work. (CREATE A TREE DIAGRAM IN YOUR NOTES AND USE IT TO SOLVE THIS PROBLEM)
