The table gives a set of outcomes and their probabilities. Let A be the event the outcome is less than 8". Find P(A) Outcome Probability 1 0.12 2 0.11 3 0.4 0.02 5 0.04 6 0.17 7 0.02 8 0.09 9 0.03 ​

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions. a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0
