Answer:
1/4
Step-by-step explanation:
Let x = number the spinner lands on
P(X = 1) = 1/4
P(X = 2) = 1/4
P(X = 3) = 1/4
P(X = 4) = 1/4
The spins are independent events as their probabilities are not affected by whether or not the other event happens
Therefore, the probability that you land on a number 2 given that your first spin landed on number 1 is still 1/4
The square root of -1 is i. So you can simplify it to 7(sqrt)-1, which becomes 7i.
