<h3>Answer:  0.1319</h3>

==========================================

Work Shown:

P(x) = (_n C_x)*(p)^x*(1-p)^{n-x}\\\\P(14) = (_{15} C_{14})*(0.8)^{14}*(1-0.8)^{15-14}\\\\P(14) = 15*(0.8)^{14}*(0.2)^{1}\\\\P(14) \approx 0.13194139533312 \\\\P(14) \approx \boldsymbol{0.1319} \\\\

Side note: you can use the nCr formula to compute _{15} C_{14}; however, it's much quicker to use the shortcut formula _{n} C_{n-1} = n. You can also use Pascal's Triangle to find the value of _{15} C_{14}

A desk is on sale for $380 which is 20% of the original price. Which equation can be used to determine the amount of money saved
elena-s [515]

Answer:

S = 380 - 380*80%

Step-by-step explanation:

Given:

  • The original price of the desk: $380
  • Discount: 20%

So, the new price of the desk after discounting is:

380(100% - 20%)

= 380*80%

= 304$

The amount of money saved: 380 - 304 = 76$

Hence, the equation can be used to determine the amount of money saved is:

Saving = 380 - 380*80%

Hope it will find you well.
