In a survey in a certain year of married couples with earnings, 99% of all husbands were employed. of all employed husbands, 77% of their wives were also employed. noting that either the husband or wife in a couple with earnings had to be employed, find the probability that the husband of an employed woman was also employed. (round your answer to four decimal places.)

Our required probability is 0.7778.

Step-by-step explanation:

Since we have given that

Probability that husbands were employed P(H) = 99%

Probability that off all husbands, wives were also employed P(H∩W) = 77%

We will use "conditional probability" to find the husband of an employed women was also employed.

Probability that the husband of an employed woman was also employed is given by

Hence, our required probability is 0.7778.

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
