Answer #1

Total number of outcomes when two dice are rolled = 6 x 6 =36

Outcomes that favor at least one 4 coming out are :

(1,4),(2,4),(3,4),(4,4),(5,4),(6,4),(4,1),(4,2)(4,3)(4,5)(4,6) [ (4,4) to be counted as one outcome)

Total number of outcomes that favor at least one 4 coming out = 11

Probability of at least one 4 coming out of two dice rolls

= Total number of outcomes that favor at least one 4 coming out / Total number of outcomes = 11/36 = 0.305555556

Probability of at least one 4 coming out of two dice rolls = 11/36 = 0.305555556
