In a paper bag, 7 of the 15 marbles are yellow. In a cloth bag, 2 of the 15 marbles are yellow. If Tim randomly draws one marble
ddd [48]

Answer :

\frac{7}{15}×\frac{2}{15} = \frac{14}{225}

Step-by-step explanation:

P(Event_{1}) = choosing yellow marble from paper bag = \frac{favourable outcomes}{possible outcomes} = \frac{7}{15}

P(Event_{2}) = choosing yellow marble from cloth bag = \frac{favourable outcomes}{possible outcomes} = \frac{2}{15}

∵ Resultant outcome is dependent upon both the events and both events are independent from each other, so we can apply intersection rule [ P(A∩B)=P(A)×P(B) ] here

∴ Probability ( Both marbles are yellow) = P(Event_{1}) × P(Event_{2}) = \frac{7}{15} × \frac{2}{15}
