Question

Anyone at all? Please help? I always give medals and such. Please

A fair coin is flipped four times. Find:
(A) the probability it will land up heads each time.
(B) The probability it will land the same way each time (slightly different from (A))

Answer 1

A would be 1/2. Let me think on B...

Answer 2

But why?

Answer 3

A would be 1/2 because there are only 2 different ways it could land. 50/50 chance of landing on each.

Answer 4

So disregard the four times right?

Answer 5

No don't. I'm saying that for each flip, it's a 1/2 chance.

Answer 6

Oh okay

Answer 7

Not sure about B though, sorry.

Answer 8

When you flip 4 coins, there are 16 outcomes in the sample space.

HHHH THHH

HHHT THHT

HHTH THTH

HHTT THTT

HTHH TTHH

HTHT TTHT

HTTH TTTH

HTTT TTTT

Answer 9

Note: Flipping 1 coin 4 times amounts to the same outcomes here as flipping one coin 4 times.

Of the 16 possible outcomes, there is only one outcome with heads each time: HHHH.

P(4 Heads) = 1/16

@Supernaturallvr24 >>> A would be 1/2 because
1/2 is not correct for Part A.
