Answer:
P(2h,2t) = 3/8
Step-by-step explanation:
If we flip a coin 4 times, there are 2^4 = 16 different outcomes. We need to see how many have 2 heads and 2 tails.
List all possible outcome and see which have 2 heads and 2 tails..
We will let H represent heads, and T represent tails
We could have...
T T T T
T T T H
T T H T
T T H H *
T H T T
T H T H *
T H H T *
T H H H
H H H H
H H H T
H H T H
H H T T *
H T H H
H T H T *
H T T H *
H T T T
The ones with a * are results with 2 heads and 2 tails...
So there are 6/16 ways this can happen, which reduces to 3/8
