Question

What is the probability that a child eats cake, given that he/she eats cookies? (1 point)

Answer 1

The probability of event A given that event B has already happened is given by the formula

$P(A|B)=\frac{P(A\cap B)}{P(B)}$

Then,

A: child eats cake.

B: child eats cookies.

Using the formula

$\begin{gathered} P(A|B)=\frac{0.1}{0.5} \\ P(A|B)=0.2 \end{gathered}$

Answer:

The probability is 0.20
