Jayden o ne a na le diranta di le 70 go tswa mo go rekiseng dinepe tse a di tserego jaaka boitlhabololo. Kgaitsadie Ava o mo neile halofo ya madi a gagwe a a le diranta di le 90 go mo thusa go reka khamera e ntšhwa e e jang diranta di le 200.

20% of 50 people think horse #2 will win the big race.  60% of the remaining people think horse #7 will win.  The rest of the people think horse #12 will win the big race.  How many people think that horse #12 will win?
Ava o neile Jayden diranta di le 90/2 = diranta di le <<90/2=45>>45.
Jaanong Jayden o na le diranta di le 70 + diranta di le  45 = diranta di le <<70+45=115>>115.
Ka jalo he, Jayden o tlhoka diranta di le 200 - diranta di le 115 = diranta di le <<200-115=85>>85 go reka khamera e ntšhwa.
#### 85 

20% of 50 people are pulling for horse #2 so that's .20*50 = <<.20*50=10>>10 people
10 out of 50 people think horse #2 will win which leaves 50-10 = <<50-10=40>>40 people
60% of 40 people think horse #7 will win so that's .60*40 = <<60*.01*40=24>>24 people
That leaves 40-24 = <<40-24=16>>16 people that think horse #12 will win
#### 16
