a)
To find
a)
Answer to Problem 47E
The probability of other education = 0.28
Explanation of Solution
Given:
P(did not complete high school) = 0.13
P(Complete high school diploma) = 0.29
P(Bachelors degree) = 0.30
The conditions of probability distribution are:
1)The probabilities should be
2)Sum of all the probabilities should be 1.
Using condition 2,
0.13+0.29+0.30+P(other) = 1
P(Other)=1-0.72 = 0.28
b)
To find probability of completing at least high school
b)
Answer to Problem 47E
The probability of completing at least high school=0.87
Explanation of Solution
Given:
P(did not complete high school) = 0.13
P(Complete high school diploma) = 0.29
P(Bachelors degree) = 0.30
Formula:
P(Ac)=1-P(A)
Using formula of complementary probability,
P(at least high school) = 1-P(not high school) = 1-0.13 = 0.87
