For a;

$P(a | sd) = p(a AND sd)/P(sd) = 0.06/(0.89) = 0.674$

For b;

$P(ds | a) = P(ds AND a)/P(a) = 0.06/0.09 =\frac{2}{3}$

on patrick's test he got 14 multiple choice questions and 6 true or false questions correct. patrick also got 1 multiple choice

So first add the multiple choice together to get 15 and the true/false together to get 10. Then add those together to get 25. Since there was 15 multiple choice, divide 15 by 25 to get 3/5. This is .8 in decimal form and to convert it to a percent multiply it by 100 to get 80%. Hope this helps!

1) 2/5 x 3 =?

Since we cannot possibly cancel the denominators, let us multiply 2 and 3.

Answer will become, 6/5.

2) 2/3x3 =?

We can cut 3 and 3.

Answer will become, 2.

3) 2/5 x 3=?

This is a repeated question and the answer remains the same as the 1st question's answer, 6/5.

4) 3/2 x 3=?

We cannot cancel the denominators, let us multiply 2 and 3.

Answer is, 9/2.
