Please solve my problem

Dear Student,

The numbers are divisibe by both 2 and 3 means no .' s divisible by 6 . No . of no .' s divisible by 6 in 1 to 50 are 8 No . of ways of selecting 3 of them are {}^{8}C_{3} Probability = \frac{{}^{8}C_{3}}{{}^{50}C_{3}} = \frac{8 \times 7 \times 6}{50 \times 49 \times 48} = \frac{1}{350} [Using {}^{n}C_{r} = \frac{n!}{r! (n - r)!}]
