Answer:
a. Jake told the negative value of the expression which cannot be equivalent to the original expression.
b. 10 - g
Step-by-step explanation:
a. The given expression is:
Multiplying through out by -, we get:
which was the expression given by Jake. Since, it is the negative of the original one, they cannot be equivalent.
b.
Hence, the answer.
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.
