Practicing Success
A pack of cards consists of 15 cards numbered 1 to 15. Three cards are drawn at random with replacement. Then, the probability of getting 2 odd and one even numbered cards is: |
$\frac{348}{1125}$ $\frac{398}{1125}$ $\frac{448}{1125}$ $\frac{498}{1125}$ |
$\frac{448}{1125}$ |
P(odd card selected) = $\frac{8}{15}$, P (even card selected) = $\frac{7}{15}$ P(2 odd, 1 even) = ${^3C}_2.(\frac{8}{15})^2.\frac{7}{15}=\frac{448}{1125}$ |
