Answer:
The answer to the question is;
The probability that there are exactly 4 successes or exactly 4 failures in the 13 rolls is .
Step-by-step explanation:
The probability of success = 1/2 =
probability of failure = 1/2
Since we have 4 success we then have 9 failures and the given probability can be solved as ₁₃C₄ × 1/2ⁿ×1/2¹³⁻ⁿ
Therefore we have
₁₃C₄ × 1/2⁴×1/2⁹ = 715/8192
That is the probability that there are exactly 4 successes or exactly 4 failures in the 13 rolls = 715/8192.
Answer:
The greatest rate of change is for <u>school A</u> as it has the greatest ratio of 2.5
Step-by-step explanation:
School A:
Ratio of male to female students,
School B:
Male students are related to female students by equation:
Where, means number of female students and
means number of male students.
Therefore, the ratio of male to female students is,
School C:
Ratio of male to female students is,
Now, rate of change of male to female students is directly proportional to the ratio of the two.
Hence, the greater the ratio, the greater the rate of change.
So, the greatest rate of change is for school A as it has the greatest ratio of 2.5
