Answer:
The given statement is false
Step-by-step explanation:
Given that an experiment repeated 5 times is more reliable than an experiment repeated 20 times.
The statement is false.
Any result found by way of experiment will be more reliable if more number of trials are done.
For example, consider toss of a coin. If we try for 2 times, we may get prob for head as 0 sometimes 1/2 or sometimes 1. This is because 2 is very short number of trials to decide. But when you increase to 10, you may get more reliable. SO if number of repititions increase, the more reliable the results would be.
Answer:
8
Step-by-step explanation:
The diagram shows 8 different endpoints, so there are 8 different possible outcomes.
You can list all outcomes:
HHH
HHT
HTH
HTT
THH
THT
TTH
TTT
where H - head, T - tail
No need to estimate. Its 19.8
It's 120*0.42 = 50.4 so 50.4 is the answer
