Doug bought 10 new country songs and 6 new rock songs for his music player. If his player randomly selects one of the new songs Doug just bought to play, what is the probability it will be a rock song?
The total number of new songs Doug bought is:
10 + 6 = 16
The number of new rock songs Doug bought is:
6
Therefore, the probability of his player randomly selecting a rock song is:
6/16 = 3/8
So, the probability of a rock song being selected is 3/8.
There are 88 balls in a bucket. The balls are numbered from 1 to 88. One ball is randomly selected from the bucket.
What is the probability that ball #55 is chosen?
To find the probability that the randomly selected song will be a rock song, we need to determine the number of rock songs and the total number of songs Doug bought.
Doug bought 10 new country songs and 6 new rock songs.
The total number of songs Doug bought is 10 + 6 = 16.
The probability of selecting a rock song can be calculated as:
Number of rock songs / Total number of songs
So, the probability of selecting a rock song is:
6 / 16 = 3 / 8
Therefore, the probability that the randomly selected song will be a rock song is 3/8.
To find the probability, we need to determine the number of favorable outcomes (i.e. the number of rock songs) and the total number of possible outcomes (i.e. the sum of rock songs and country songs).
In this case, Doug bought 10 new country songs and 6 new rock songs, resulting in a total of 10 + 6 = 16 songs.
The number of favorable outcomes (rock songs) is 6.
Therefore, the probability of the player randomly selecting a rock song is 6/16, or simplified, 3/8.
So, the probability that a randomly selected song will be a rock song is 3/8.
