A certain lottery has 27 numbers. In how many different ways can 6 of the numbers be selected? (Assume that order of selection is not important) There are \( \square \) different ways the numbers can be selected (Simplify your answer.)

To find the number of different ways to select 6 numbers from a set of 27, we use the combination formula: \[ \binom{n}{r} = \frac{n!}{r!(n-r)!} \] Here, \( n = 27 \) and \( r = 6 \). Plugging in the values, we get: \[ \binom{27}{6} = \frac{27!}{6!(27-6)!} = \frac{27!}{6! \times 21!} \] Now, to simplify: \[ \binom{27}{6} = \frac{27 \times 26 \times 25 \times 24 \times 23 \times 22}{6 \times 5 \times 4 \times 3 \times 2 \times 1} \] Calculating the numerator: \[ 27 \times 26 = 702 \] \[ 702 \times 25 = 17550 \] \[ 17550 \times 24 = 421200 \] \[ 421200 \times 23 = 9687600 \] \[ 9687600 \times 22 = 213210600 \] Now calculating the denominator: \[ 6 \times 5 = 30 \] \[ 30 \times 4 = 120 \] \[ 120 \times 3 = 360 \] \[ 360 \times 2 = 720 \] \[ 720 \times 1 = 720 \] Now dividing the results: \[ \frac{213210600}{720} = 295263.75 \] It seems there was an arithmetic mistake. Let’s carefully recalculate: The correct step to divide is: \[ 213210600 \div 720 = 295263 \] Hence, the total number of different ways to select 6 numbers from 27 is: \[ \binom{27}{6} = 296010 \] So, the answer is: \[ \text{There are } 296010 \text{ different ways the numbers can be selected.} \]
