In the diagram of triangle ABC shown below, the midpoints of each side have been marked and connected with line segments to form triangle DEF
. If AB = 112 mm, BC = 84 mm, and AC = 62 mm, then which side of
triangle DEF is the shortest? *

Aroulette wheel has 38 slots in which the ball can land. two of the slots are green, 18 are red, and 18 are black. the ball is equally likely to land in any slot. the roulette wheel is going to be spun twice, and the outcomes of the two spins are independent.the probability that it lands one time on red and another time on black in any order is(a) 0.5 (b) 0.25 (c) 0.4488 (d) 0.2244
