Question

Two coins are tossed once . What is the probability of getting at least one T?

Answer 1

(T,T),(T,H),(H,T),(H,H)=4

atleast one tell= 3

then the probability is 3/4

Answer 2

All outcome for 2 coins:

h,h

h,t

t,h

t,t

3 out of 4 possibilities have at least one head, so the chance is 3/4, or 75%

hope it is helpful
