Suppose that $P(A)=.4$ and $P(A \cap B)=.12$ a. Find $P(B \mid A)$. b. Are events $A$ and $B$ mutually exclusive? c. If $P(B)=.3,$ are events $A$ and $B$ independent?

Step 1
We are given $P(A) = 0.4$ and $P(A \cap B) = 0.12$. Plugging these values into the formula, we get: $P(B \mid A) = \frac{0.12}{0.4} = 0.3$ Show more…

$A$ and $B$ are mutually exclusive events, with $P(A)=.3$ and $P(B)=.4$. a. Find $P(A \mid B)$. b. Are $A$ and $B$ independent events?
Suppose that $P(A)=.4$ and $P(B)=.2 .$ If events $A$ and $B$ are independent, find these probabilities: a. $P(A \cap B)$ b. $P(A \cup B)$

For two events $\mathrm{A}$ and $\mathrm{B}$, if $\mathrm{P}(\mathrm{a})=\mathrm{P}(\mathrm{A} / \mathrm{B})=\frac{1}{4}$ and $\mathrm{P}(\mathrm{B} / \mathrm{A})=\frac{1}{2}$ then (a) $\mathrm{A}$ and $\mathrm{B}$ are independent (b) A and B are mutually exclusive (c) $\mathrm{P}\left(\mathrm{A}^{\prime} \mid \mathrm{B}\right)=\frac{3}{4}$ (d) $\mathrm{P}\left(\mathrm{B}^{\prime} \mid \mathrm{A}^{\prime}\right)=\frac{1}{2}$
