$\frac{15}{48} = \frac{5}{16} = .3125$ $15/48 = 5/16 = .3125$

Explanation:

The sample space of $48$ $48$ can be drawn as follows:

$123456$ $" " 1" "2" "3" "4" "5" "6$
$11, 11, 21, 31, 41, 51, 6$ $1" "1, 1" "1, 2" "1, 3" "1, 4" "1, 5" " 1, 6$

$22, 12, 22, 32, 42, 52, 6$ $2" "2, 1" "2, 2" "2, 3" "2, 4" "2, 5" "2, 6$

$33, 13, 23, 33, 43, 53, 6$ $3" "3, 1" "3, 2" "3, 3" "3, 4" "3, 5" "3, 6$

$44, 14, 24, 34, 44, 54, 6$ $4" "4, 1" "4, 2" "4, 3" "4, 4" "4, 5" "4, 6$

$55, 15, 25, 35, 45, 55, 6$ $5" "5, 1" "5, 2" "5, 3" "5, 4" "5, 5" "5, 6$

$66, 16, 26, 36, 46, 56, 6$ $6" "6, 1" "6, 2" "6, 3" "6, 4" "6, 5" "6, 6$

$77, 17, 27, 37, 47, 57, 6$ $7" "7, 1" "7, 2" "7, 3" "7, 4" "7, 5" "7, 6$

$88, 18, 28, 38, 48, 58, 6$ $8" "8, 1" "8, 2" "8, 3" "8, 4" "8, 5" "8, 6$

Eliminate columns $4, 5, 6$ $4, 5, 6$

Those that have sums $\geq 6$ $>= 6$ in column 1: $4$ $4$
Those that have sums $\geq 6$ $>= 6$ in column 2: $5$ $5$
Those that have sums $\geq 6$ $>= 6$ in column 3: $6$ $6$

Those that have sums $\geq 6$ $>= 6$ is $4 + 5 + 6 = 15$ $4+5+6 = 15$

$P (\geq 6) = \frac{15}{48} = .3125$ $P(>= 6) = 15/48 = .3125$
