Ber [7]

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

WARRIOR [948]

Hey!

The formula for finding volume of a cylinder is: π · r² · h

r = 8 \\ r^{2} = 8 \times 8 = 64

h = 3

Now multiply

\pi \times 64 \times 3 = 192\pi

<em>Your answer is B)192π units³</em>

Good luck and hope this helps! :)
