Answer:
E) 60
Explanation:
total possible combinations for the board games = N! / K!(N-K)!
- N = total number of items
- K = size of the subgroup
6! / [3! x (6-3)!
]
6! = 6 x 5 x 4 x 3 x 2 x 1 = 720
3! = 3 x 2 x 1 = 6
6! / [3! x (6-3)!
] = 720 / (6 x 6) = 720 / 36 = 20
total possible combinations for the ball = 3! / 1!2! = 6 / 2 = 3
total combinations for both 1 ball and 3 games = 20 x 3 = 60
