Question

Use the frequency distribution to the​ right, which shows the number of voters​ (in millions) according to​ age, to find the probability that a voter chosen at random is in the given age range. not between 25 and 34 years old Ages of voters Frequency 18 to 20 6.8 21 to 24 11.4 25 to 34 21.1 35 to 44 22.8 45 to 64 58.5 65 and over 29.2 The probability is nothing. ​(Round to three decimal places as​ needed.)

Answer 1

Solution:-

Given data :

Ages of voters	Frequency
18 to 20	6.8
21 to 24	11.4
25 to 34	21.1
35 to 44	22.8
45 to 64	58.5
65 and over	29.2

Here we have to calculate the probability that a voter chosen at random is in the given age range. not between 25 and 34 years old.

i.e, Probability = P(not between 25 and 34 years old)

Probability = 1 - P(between 25 and 34 years old)

Hence, the probability that a voter chosen at random is in the given age range. not between 25 and 34 years old is 0.859.
