For the standard normal distribution shown on the right, find the probability of z occurring in the indicated region. 0.61 -0.93 z A normal curve is over a horizontal z-axis. Vertical line segments extend from the horizontal axis to the curve at negative 0.93 and 0.61. The area under the curve between negative 0.93 and 0.61 is shaded. The probability is nothing. (Round to four decimal places as needed.)
