Question
$\mathrm{A}$ and $\mathrm{B}$ are independent events, and $P(\mathrm{A})=0.4$ and $P(\mathrm{A} \text { and } \mathrm{B})=0.5 .$ Find $P(\mathrm{B})$
Step 1
This means that the probability of both A and B occurring is the product of their individual probabilities. This can be written as: \[P(A \text{ and } B) = P(A) \times P(B)\] Show more…

$\mathrm{A}$ and $\mathrm{B}$ are independent events, and $P(\mathrm{A})=0.7$ and $P(\mathbf{B})=0.4 .$ Find $P(\mathrm{A} \text { and } \mathbf{B})$
Let A and B be events with P(A) = 0.5, P(B) = 0.4. Assume that A and B are independent. Find P(A and B).
