So, in the given question, a fair coin is toast three times.
00:06
A fair coin is toast three times, right? and in the question we are told to find the probability that at least one head turns up.
00:30
So, this is the probability that we have to calculate.
00:36
So we should know that the total number of outcomes that we will have total number of outcomes we will have as equal to 2 cube which is equal to 8.
00:53
So the outcomes where we will have at least one head can be listed as 8.
01:01
H, h, where there are all heads.
01:08
They can be hh, h, h, t, h, h, t, h, h, h, t, h, h, h, h, h, h, t, h, t, h, and t, t, then we have, that's it right, one, two, three, four, five, six, seven...
