(10 points) List all the possible outcomes of a four color spinner (yellow, blue, green, orange) that is spun twice in a row. What is the probability of spinning the same color twice in a row?

Help, please and thank you :)

Assume that adults have iq scores that are normally distributed with a mean of mu equals 100 and a standard deviation sigma equals 20. find the probability that a randomly selected adult has an iq between 80 and 120.assume that adults have iq scores that are normally distributed with a mean of mu equals 100 and a standard deviation sigma equals 20. find the probability that a randomly selected adult has an iq between 80 and 120.
