Answer: Our required probability is 0.99338.
Step-by-step explanation:
Since we have given that
n = 100
p = 0.200
So,
So, we can apply normal approximation.
Mean = 20
Standard deviation =
Since
So, Probability that fewer than 30 but a packet after testing a free sample is given by
Hence, our required probability is 0.99338.
x < 22.5; Samuel has less than 22.5 minutes to finish the race in the estimated time.
<h3>What amount of time Samuel left for the race?</h3>The given inequality is-
From here, we define the variable x.
x = Number of the minutes left for the race
From here we can find the value of x
We have then:
Hence, Samuel has less than 22.5 minutes to finish the race in the estimated time.
