the table below shows the registered Democrats and Rebuplicans in a school
Women men
Democrates 152 88
Republicans 98 122
a) find the probbility that a randomly selected person from the school is a male republican.
b) find the probbility that a randomly selected person from the school is registered republican.
c) find the probability that a randomly selected democrat is a woman.
d) find the probability that a randomly selected man is a democrat.
e) find the probability that a randomly selected woman is a republican.
I will do one.
e) Pr=98/(98+152)
I will gladly critique your work.
thanks
To find the probabilities in this scenario, we need to understand the total number of people in the school, as well as the number of individuals in each category.
a) To find the probability that a randomly selected person from the school is a male Republican, we divide the number of male Republicans (122) by the total number of people in the school (152 + 88 + 98 + 122):
Probability = Number of male Republicans / Total number of people
Probability = 122 / (152 + 88 + 98 + 122)
b) To find the probability that a randomly selected person from the school is a registered Republican, we need to add the number of male Republicans and female Republicans, and divide it by the total number of people in the school:
Probability = (Number of male Republicans + Number of female Republicans) / Total number of people
Probability = (98 + 122) / (152 + 88 + 98 + 122)
c) To find the probability that a randomly selected Democrat is a woman, we need to divide the number of female Democrats (152) by the total number of Democrats (152 + 88):
Probability = Number of female Democrats / Total number of Democrats
Probability = 152 / (152 + 88)
d) To find the probability that a randomly selected man is a Democrat, we divide the number of male Democrats (88) by the total number of men (88 + 122):
Probability = Number of male Democrats / Total number of men
Probability = 88 / (88 + 122)
e) To find the probability that a randomly selected woman is a Republican, we divide the number of female Republicans (98) by the total number of women (152 + 98):
Probability = Number of female Republicans / Total number of women
Probability = 98 / (152 + 98)
Now, you can substitute the values into the formulas to find the probabilities!
