Dear Student

In throwing a dice, total possible outcomes = {1, 2, 3, 4, 5, 6}

n(S) = 6

For two dice, n(S) = 6 x 6 =36

Favourable cases where sum is 10 or more with 5 on first dice {(5,5), (5,6)}

Event of getting sum is 10 or more with 5 on first dice = n(E) = 2

Probability of getting sum of 10 or more with 5 on first dice = n(E)/n(S) = 2/36 = 1/18
