Answer:
Buy the batteries and stereo online:
4.99*2= $9.98 +$90 = $99.98
6.99-5.00 = $1.99
99.98+1.99=$101.97
3Cds in store
7.97*3= $23.85
5% tax = 1.19
10% off = 2.39
$23.85 - $1.19= $22.66
22.66 + 101.97= $124.63
All in store:
12+100+23.85= 135.85 - 6.45 = $129.40
All online:
9.98 + 90 + 26.85= 126.85 +$1.99 = 128.84

The number could be anything because whatever it is it can be quadrupled
This is a problem in binominal probability. Either the rented film is a comedy or is not a comedy (binary outcomes). the probability that the rented film is a comedy is 52%.
You must calculate and add together three probabilities to derive a final answer:
binompdf(7,0.52,0), binompdf(7,0.52,1) and binompdf(7,0.52,2).
Can you do this? Let me know if you need further help with this problem.
The answer is no solution because 2 is not equal to -2
