Question

How to complete a tree diagram?
The question:
"When Ivan goes to school in winter, the probability that he wears a hat is 5/8. If he wears a hat, the probability that he wears a scarf is 2/3. If he does not wear a hat, the probability that he wears a scarf is 1/6.

Answer 1

the probability that he wears a hat is 5/8

so on the branch that says "hat" you write 5/8

the "no hat" branch is 3/8 since 1 - (5/8) = 3/8

Answer 2

Then it states

" If he wears a hat, the probability that he wears a scarf is 2/3"

so on the "hat" branch, we'll have 2/3 for scarf and 1/3 for no scarf

Answer 3

Finally, "If he does not wear a hat, the probability that he wears a scarf is 1/6" means we have 1/6 on the scarf (under no hat) and 5/6 for "no scarf"
