3,000,000/12 = 250,000 quakes per year
3,000,000/365 = 8219.2 quakes per day
First let’s see how many letter tiles exist in a set.
9 + 2 + 2 + 4 + 12 + 2 + 3 + 2 + 9 + 1 + 1 + 4 + 2 + 6 + 8 + 2 + 1 + 6 + 4 + 6 + 4 + 2 + 2 + 1 + 2 + 1 + 2 = 100 tiles
Now let’s focus on the letters we need. A-9 B-2 C-2 D-4 E-12 F-2 G-3 H-2 I-9 J-1 K-1 L-4 M-2 N-6 O-8 P-2 Q-1 R-6 S-4 T-6 U-4 V-2 W-2 X-1 Y-2 Z-1 Blank-2
(2/100)(4/99)(12/98) = 96/970,200 = 4/40,425
First let’s see what percent of the vehicles would still be ON the road.
(2/3)(9/10) = 6/10 = 60%
Thus, 100 – 60 = 40% of the vehicles would be kept OFF the road.
