djyliett [7]

To solve this question, use the Binomial probability formula.

The formula is given by

$^nC_xp^x(1-p)^{n-x}$

Where:

n = the number of trials

x = the sample we aim to try

p = the probability of success

In this question:

n = 16

x = 9

p = 0.5

Substituting in the equation:

$\begin{gathered} ^nC_xp^x(1-p)^{n-x} \\ ^{16}C_9*0.5^9(1-0.5)^{16-9} \\ \end{gathered}$

And the combination formula:

$^nC_x=\frac{n!}{(n-x)!*x!}$

Then:

$\begin{gathered} \frac{16!}{(16-9)!*9!}*0.5^9(1-0.5)^{16-9} \\ \frac{16!}{7!*9!}*0.5^9*0.5^7 \\ 11440*0.00195*0.0078 \\ =0.1746 \end{gathered}$

Answer: The probability is 0.1746.

A grocery store is offering a 50% discount off a $4.00 box of cereal. You also have a $1.00 off coupon for the same cereal. Use

s344n2d4d5 [400]

After because if you use it before the discount then the final price will be 1.50 but if you use it after the discount, then the final price is 1 dollar . 4 dollar with 50% discount is 2 dollar, and 2-1 is 1. 4-1 is 3 and 3 dollar with 50% discount is 1.50 dollar

I solved it this way. I’m guessing you should replace the zeros with these numbers here.
