Question

4) We toss twice symmetric tetrahedral cube with sides: •, ••, •••, ••••. Let A - sum of dots is 4; B in second toss the number of dots \textgreater 3. Find $P(A)$, $P(B)$, $P(A \cap B)$, $P(A \cup B)$, $P(A')$, $P(B')$. Are A & B independent?

Step 1

There are 4 possible outcomes: 1+3, 2+2, 3+1, and 4+0. Each outcome has a probability of 1/6 * 1/6 = 1/36. Therefore, P(A) = 4/36 = 1/9. Show more…
