Hello students, according to the given question, we have to find out the probability values.
00:07
Here from given data probability of a will be denoted as the probability of the residence of a household, residence of a household one own two cars and probability of b is denoted as probability of probability that the annual income the annual income is greater than 25 ,000.
00:46
Now we can write probability of a given b is given 0 .8 and probability of a is given 0 .70 and probability of b is equal to 0 .60.
01:01
Now we have to find probability of a bar given b bar.
01:06
So, that is equal to probability of a bar intersection b bar divided by probability of b bar that is equal to 1 minus probability of a union b is divided by 1 minus probability of b.
01:22
Now we have to calculate a union b.
01:25
So, before that it was given probability of a given b is equal to 0 .8 that implies probability of a intersection b divided by probability of b is equal to 0 .8 then probability of a intersection b is equal to 0 .8 into probability of b is 0 .60.
01:49
So, which is equal to 0 .48...
