Q:

Chandler has 4 coins if he flips one right after the other what is the probability that the results will have 2 heads and 2 tails

Accepted Solution

A:
Answer:P(2h,2t) = 3/8Step-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 tailsWe could have...T T T TT T T HT T H TT T H H      *T H T T T H T H      *T H H T      *T H H HH H H HH H H TH H T H H H T T      *H T H H H T H T      *H T T H      *H T T TThe 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
