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.
Answer:
Necessarily it could be anything
Step-by-step explanation:
If you want a repeating decimal digit of 0 it's going to be all decimals just to a different place like the tenths place. For example 0.5 is also 0.500000000000... That is why pretty much every decimal has a repeating digit of 0.
Answer: The answer is a decimal.
