In a given year every 100 babies born, there were 6 more boys than girls. If we were to randomly pick a child from a representative group, what is the probability of picking a girl?
So there were 53 boys and 47 girls
prob(girl) = 47/100 or .47
To determine the probability of picking a girl, we first need to find the ratio of boys to girls in the representative group.
Given that in a year, for every 100 babies born, there are 6 more boys than girls, we can set up an equation:
Number of boys = Number of girls + 6
Since there are 100 babies in total, we can express this equation as:
Boys + Girls = 100
Substituting the first equation into the second equation, we get:
(Girls + 6) + Girls = 100
2Girls + 6 = 100
2Girls = 100 - 6
2Girls = 94
Girls = 94 / 2
Girls = 47
So, there are 47 girls in the representative group.
To find the probability of picking a girl, we divide the number of girls by the total number of babies in the representative group:
Probability = Number of girls / Total number of babies
Probability = 47 / 100
Therefore, the probability of picking a girl from the representative group is 47/100 or 0.47.
To calculate the probability of picking a girl from a representative group, we need to consider the ratio of boys to girls in the group.
Given that every 100 babies born in a year, there are 6 more boys than girls, we can assume that the ratio of boys to girls is 106:100 (since there are 6 more boys than girls in 100 babies).
To calculate the probability of picking a girl, we need to determine the proportion or ratio of girls to the total number of children in the group. In this case, the proportion of girls would be 100 out of the total number (100 boys + 100 girls), giving us a ratio of 100:200, which simplifies to 1:2.
Therefore, the probability of randomly picking a girl from the group would be 1/3 or approximately 0.3333.
