<u>Probabilities</u>
One approach to estimating the probability of occurrence of an event is to record the number of times that event happens (e) and compare it with the total number of trials (n).
The probability can be estimated with the formula:
And the probability that the event doesn't occur is
Q = 1 - P
Paulo arrives on time to school e=53 times out of n=79 times. The probability that he arrives on time is:
P = 0.67
And the probability he arrives late is:
Q = 1 - 0.67 = 0.33
Answer:
656.4671128 nanometer
Step-by-step explanation:
1 nano meter = 10 ^-9 meter
Now given 6.564671128 × 10^ -7 meters
so in nano meter ,
= 656.4671128 × 10^-9 meter
= 656.4671128 nanometer Answer
