Answer :
0.53
Step-by-step explanation:
Given the following :
Probability of female = probability of success on a single trial = 0.51
Number of babies = 80
Probability that more than half of the babies are female : p(X >80/2) = P(X > 40)
The problem can be solved using the binomial probability function :
P(X > 40) = [ p(X= 41) + p(X= 42) +.... +p(X= 80)]
In other to save computation time, we can use the binomial probability calculator
Hence ; P(X > 40) = 0.527 = 0.53
Answer:
1. 5040
2. 20
Step-by-step explanation:
1. using the formula for permutation
nPr=n!/(n-r)!
10P4 = 10!/(10-4)!
=10*9*8*7*6!/6!
then we are left with
=10*9*8*7
=5040
2.using the formula for combination
nCr=n!/(n-r)!r!
6C3=6!/(6-3)!3!
=6*5*4*3!/3!3!
=6*5*4/3*2*1
=20
Since you are given the area, we can solve for radius with this equation:
The radius is 11, so the diameter must be 2 times that, which is 22. With the correct units, the answer is
22 units²
Answer:
$50
Step-by-step explanation:
Weekly paycheck to be deposited = 70%
This week's deposit = $35
Therefore, we have to determine how much is Alex weekly paycheck.
To find this, we have to use unitary method.
According to the Question
Total weekly paycheck = (total deposit/ percentage to be deposited)
Therefore, Weekly paycheck = ($35/70%)
Weekly paycheck = $50.
It means Alex gets $50 per week.
