Step-by-step explanation:
hru and thank u for this question
This problem is an example of binomial probability. In
this case, we can use the formula:
P (r) = [n! / (n – r)! r!] p^r q^(n-r)
where,
n = total number of babies = 11
r = selected number of babies
p = success of being a girl = 0.5
q = 1 – p = 1 – 0.5 = 0.5
Since we are asked to find for the P (r less than or
equal 9), therefore:
P (r less than or equal 9) = 1 – [P(11) + P(10)]
P(11) = [11! / (11 – 11)! 11!] 0.5^11 * 0.5^(11-11) = 4.8828
* 10^-4
P(10) = [11! / (11 – 10)! 10!] 0.5^10 * 0.5^(11-10) = 5.3711
* 10^-3
Therefore:
P (r less than or equal 9) = 1 – [4.8828 * 10^-4 + 5.3711
* 10^-3]
P (r less than or equal 9) = 0.994
The closest answer is letter C:
C = 509/512 = 0.994
Answer:
1) A, B, C
2) D, E, F
3) Q
4) R, L(but lowercase), m, S, n
To answer this question, we need to find a common denominator for these two fractions, i.e. how can we write 7/12 in the same way as 1/3?
The common denominator for these fractions will have to be 12, because 7/12 cannot be simplified anymore - 7 is a prime number. So we'll convert 1/3 into 12ths. To do this:
1 ---> Multiply the top by 4, because we multiplied the bottom by 4
--
3 ---> Multiply the bottom by 4 to get 12
So 1/3 = 4/12
7/12 - 4/12 = 3/12 ---> Complete the subtraction
3/12 can be simplified, as both 3 and 12 are divisible by 3.
3 ---> Divide by 3
--
12 ---> Divide by 3
=
1
--
4
And 1/4 is your answer.
Rational, or integer. I am not sure sorry
