Answer:
The probability that 8 mice are required is 0.2428.
Step-by-step explanation:
Given : A scientist inoculates mice, one at a time, with a disease germ until he finds 3 that have contracted the disease. If the probability of contracting the disease is two sevenths.
To find : What is the probability that 8 mice are required? The probability that that 8 mice are required is nothing ?
Solution :
Applying binomial distribution,

Where, p is the probability of success 
q is the probability of failure q=1-p, 
n is total number of trials n=8
r=3
Substitute the values,




Therefore, the probability that 8 mice are required is 0.2428.
Answer: Q#1:0.26
Step-by-step explanation: just round it up
Answer:
That is correct.
Step-by-step explanation:
2 times 10=20
4 times 1=4
5 times 0.1=0.5
8 times 0.01=0.08
20+4+0.5+0.08=24.58
That is correct.
