Answer: The probability that exactly 2 insects will survive = 0.2501
Step-by-step explanation:
Given: A certain insecticide kills 80% of all insects in laboratory experiments.
The probability that a particular insect survives= 1-0.80=0.20
Sample size: n=14
Binomial probability distribution:
, where x= number of successes , p=probability of success in each trial, n= sample size.
The probability that exactly 2 insects will survive =
Hence, the probability that exactly 2 insects will survive = 0.2501
Answer:
Option b
or
Step-by-step explanation:
The absolute value is a function that transforms any value x into a positive number.
Therefore, for the function x> 0 for all real numbers.
Then the equation:
has two cases
if
(i)
if
(ii)
We solve the case (i)
We solve the case (ii)
Then the solution is:
