Easy -1.3 This is a straightforward reading comprehension question from a probability distribution diagram. Students simply need to identify the relevant bars (Y = 1, 2, 3) and add their probabilities. It requires no problem-solving, calculation skills, or conceptual understanding beyond basic probability notation—purely mechanical execution of 'read and add.'
13 The diagram below shows the probability distribution for a discrete random variable \(Y\).

Find \(\mathrm { P } ( 0 < Y \leq 3 )\).
Circle your answer.
\(0.40 \quad 0.42 \quad 0.58 \quad 0.66\)
