13 The number of pots of yoghurt, \(X\), consumed per week by adults in Milton is a discrete random variable with probability distribution given by

\(\boldsymbol { x }\)	0	1	2	3	4	5	6	7 or more
\(\mathbf { P } ( \boldsymbol { X } = \boldsymbol { x } )\)	0.30	0.10	0.05	0.07	0.03	0.16	0.09	0.20

Find \(\mathrm { P } ( 3 \leq X < 6 )\) Circle the correct answer. \(0.26 \quad 0.31 \quad 0.35 \quad 0.40\)
