In other words, carl's losing odds are 7 : 5, so his winning odds will be 5 : 7
So if they play (7+5=12) 12 times, carl will win 5 times.
To find probability that carl will beat his friend, we take the probability of Carl winning. Simple!
The probability is 5/ 12
Part a: Cost of downloading album B = 13.3 euros
Part b: Cost of downloading album B = 12.6 euros
Number of tracks in album A = 11 tracks
The total cost of downloading album A = 10.45 euro
Cost of each track on album A = Total cost of album/Number of tracks in the album
= 10.45/11
= 0.95 euro
Part a:
Number of tracks in album B = 14 tracks
Cost of album B = Number of tracks in album B * Cost of each track
= 0.95*14
= 13.3 euros
Part b:
The cost of 5 tracks on album B is 5p less therefore, the cost of 5 tracks will be 0.90*5 = 3.60 euros
The cost of 9 tracks on album B is 5p more therefore, the cost of 9 tracks will be = 1*9 = 9 euros
The total cost of downloading album B = 9+3.6 = 12.6 euros

Answer:
Step-by-step explanation:
You would add probabilities if you want to find out if one event or another could happen. For example, if you roll a die, and you wanted to know the probability of rolling a 1 or a 6, then you would add the probabilities:
Probability of rolling a 1: 1/6
Probability of rolling a 6: 1/6
So the probability of rolling a 1 or a 6 is 1/6 + 1/6 = 2/6 = 1/3.
