a)
Answer to Problem 46E
The probability of other = 0.09
Explanation of Solution
Given:
Language: | English | French | Asian/Pacific | Other |
Probability | 0.63 | 0.22 | 0.06 | ? |
The conditions of probability distribution are:
1)The probabilities should be
2)Sum of all the probabilities should be 1.
Using condition 2,
0.63+0.22+0.06+P(other) = 1
P(Other)=1-0.91 = 0.09
b)
To find probability of not English.
b)
Answer to Problem 46E
The probability of not English=0.37
Explanation of Solution
Given:
Language: | English | French | Asian/Pacific | Other |
Probability | 0.63 | 0.22 | 0.06 | 0.09 |
Formula:
P(Ac)=1-P(A)
Using formula of complementary probability,
P(not English) = 1-P(English) = 1-0.63 = 0.37
c)
To find probability that language other than English or French.
c)
Answer to Problem 46E
The probability is 0.15
Explanation of Solution
Given:
Language: | English | French | Asian/Pacific | Other |
Probability | 0.63 | 0.22 | 0.06 | 0.09 |
Formula:
The probability that Canadians mother tongue language is other than English or French means the language Asian/Pacific or Other.
Using formula,
