Question

When a fair coin is​ flipped, the probability of its landing heads​ (H) is 0.500.50 and the probability of its landing tails​ (T) is also 0.500.50. Make a list of all the possible arrangements for flipping a fair coin​ twice, using H for heads and T for tails. Find the probabilities of each arrangement.

Answer 1

probability (HH) = 1/4 = 0.25

probability (HT) = 1/4 = 0.25

probability (TH) = 1/4 = 0.25

probability (TT) = 1/4 = 0.25

Explanation:

given data

probability heads​ (H) is 0.50

probability heads​ (T) is 0.50

to find out

the probabilities of each arrangement

solution

when coin toss there are two outcome that is head or tail

and then flip 2 time

possibility are HH HT TH TT

so

probability (HH) = 1/4 = 0.25

probability (HT) = 1/4 = 0.25

probability (TH) = 1/4 = 0.25

probability (TT) = 1/4 = 0.25
