Given that p (b|a) = 0.75 and p (a) = 0.35, what is p (b and a)

1.0125

Step-by-step explanation:

Since b/a is 0.75 and a is given as 0.35

Then let's start by solving for b

Ok ... how

b/a=0.75

a=0.35

Then make b the subject of formula

b=0.75*a

Then substitute the value of a

b=0.75*0.35

b=0.2625

Let's continue

b and a means b + a

0.75+0.2625

1.0125

Therefore the final answer is 1.0125
