GEOMETRY HELP Which of the following are dependent events?
lisabon 2012 [21]

Answer:

Option C

Step-by-step explanation:

A and B are said to be independent of

P(A intersection B) = P(A)*P(B).

Or if drawing is done with replacement, etc.

A) P(drawing a king) = 4/52 = 1/13

IF we replace again drawing a kind is the same 1/13

Hence independent

B) Coin flipping each toss is obviously independent of the other as prob of getting tail in a fair coin is 1/2 irrespective of the previous outcomes

C) Without replacement is not independent

Since first prob = 4/52 and second would be 3/51 not the same as before

D) Rolling a die is independent as getting a 2 in any throw is always the same.

C is answer

18-5y=y+4 how do you do this
Ipatiy [6.2K]
18 - 5y = y + 4
Step 1: Simplify both sides of the equation.
18 - 5y = y + 4
Simplify: (show steps)
-5y + 18 = y + 4
Step 2: Subtract y from both sides
-5y + 18 - y = y + 4 - y
6y + 18 = 4
Step 3: subtract 18 from both sides
-6y + 18 - 18 = 4 - 18
-6y = -14
Step 4: divide both sides by -6
-6y/-6 = -14/-6
y=7/3
