see first you tossed coin probability of head is 1/2.
Again you tossed coin probability of head is 1/2.
Now simplify the equation by adding 1/2+1/2= 2/4 => 1/2.
Two attempts was just to confuse the question

Brother with no offence, if you add 1/2+1/2=2/2 which is equal to 1. if in the question or was written instead of "and" than we could use addition formula but because of word and we have to multiply both the probabilities.
