Answer:
"dependent events since P(A and B) is not equal to P(A)* P(B)"
Step-by-step explanation:
For 2 events to be independent,
P(A and B) = P(A) * P(B)
<em>IF NOT EQUAL, then they are dependent events.</em>
<em />
<em>P(A and B) = 0.52 (given), also</em>
<em>P(A) * P(B) = 0.73*0.61=0.4453</em>
<em />
<em>Thus, P(A and B) ≠ P(A) * P(B), thus they are dependent events.</em>
Answer:
For the first one the value of X will be 3 and the second one the value of X will be 5.5
Step-by-step explanation:
All you're really doing for expressions like this are dividing the whole number into the number with the variable. for example, i took 5 and divided it into 15x which gave me 3 so the X will equal 3. Hope I helped
