Question

To win a particular lottery game, it is necessary to match numbers on 5 balls that are randomly picked from 65 balls numbered 1-65 and the number on a special black ball that is picked from 10 other balls numbered 0-9. What is the probability that a single lottery ticket will match 2 balls and the special black ball.

Answer 1

Answer: $5.34*10^{-5}$

Step-by-step explanation:

given data:

number of balls = 65.

special black ball that is picked from 10 other balls = numbered 0-9.

Solution:

probability that a single lottery ticket will match 2 balls and the special black ball.

$= 65C2*9C1\\\\= 18720\\\\=\frac{1}{18720} \\\\= 5.34*10^{-5}$
