If two dice are rolled, what is the probability that the sum of the dots on the upward faces is 10

After t seconds, a ball tossed in the air from the ground level reaches a height of h feet given by the equation h = 144t-16t^2. after how many seconds will the ball hit the ground before rebounding?

If t17 = 3 (t5) in an arithmetic progression, find t1 in terms of d.
