1. Check the tree diagram in the picture attached.

2. The blue segment represents "on time"
The red segment represents "not on time"

3. blue - blue - red represents the case 1st on time, 2nd on time, 3rd not on time.

the combined probability is 90/100*90/100*10/100=9/10*9/10*1/10=99/1000=0.099

4. Remark with a tree diagram we can tell anything asked about the probability of an experiment.
