To find the probability of selecting a female from the group, we need to calculate the ratio of the number of females to the total number of people in the group.
The number of females under the age of 21 is 10.
The number of females aged between 21 and 30 is 7.
The number of females over the age of 30 is 6.
Total number of females = 10 + 7 + 6 = 23
Now, let's calculate the total number of people in the group:
The number of males under the age of 21 is 12.
The number of males aged between 21 and 30 is 8.
The number of males over the age of 30 is 9.
Total number of males = 12 + 8 + 9 = 29
Total number of people in the group = Total number of males + Total number of females = 29 + 23 = 52
Probability of selecting a female = Number of females / Total number of people
= 23 / 52
= 0.4423 (rounded to four decimal places)
Therefore, the probability that if one person is selected at random from the group, this person will be female is approximately 0.4423.
12 males under the age of 21.
10 females under the age of 21.
8 males aged between 21 and 30.
7 females aged between 21 and 30.
9 males over the age of 30.
6 females over the age of 30.
Calculate the probability that, if one person is selected at random from the group this person will be female:
