what are the letters on the spinner

Answer 1

A spinner is divided into four equal regions. The
spinner is spun two times.

i. Create a tree diagram

|

|         \           \           \

N            E            E            T      This is the choices.   After first spin.

|  \  \  \     |  \  \  \     | \ \ \       |  \ \ \

N E E T  N E E T  N E E T  N E E T       Second spin line

ii. looking at the first spin line there is 2/4 chance for E.  or .500

iii. looking at the second spin line there is a 4/16 chance of E-E.  or .250

ii. What is the probability of 2E’s? Leave your solution corrected to 3 decimal places.
iii. What is P(same letter on both spins)? Leave your solution corrected to 3 decimal places.
