There are fifty apples left on a tree and ten of them have worms. We pick five apples at random. What is the probability that at least one of them is without a worm?
\( 1-\frac{\binom{10}{5}}{\binom{50}{5}}\doteq 0{.}9999 \)
\( 1-\frac{\binom{10}{1}}{\binom{50}{5}}\doteq 1{.}0000 \)
\( 1-\frac{\binom{10}{1}\binom{40}{4}}{\binom{50}{5}}\doteq 0{.}5687 \)
\( 1-\frac{\binom{40}{5}}{\binom{50}{5}}\doteq 0{.}6894\)
