What is the solution set for 4x - 3= 2x +5, given the replacement set {2, 3, 4, 5}?

step-by-step explanation:

if we roll   two fair six-sided dice, then the outcomes to get the sum atleast 9 are: (6,3), (3,6), (6,4), (4,6), (6,5), (5,6), (5,5), (6,6)

thus, the number of outcomes for the sum to be greater than or equal to 9 = 8

the total possible outcomes = 36

then the probability that the sum is 9 or higher is given by : -

hence, the   probability that the sum is 9 or higher is
