Far coin is tossed four times so four times a coin is tossing means while tossing you will be having head or tail so it is the event of two so here it is four times therefore two power four which is nothing but 16 will be the process of obtaining while the coin is tossed four times the possibilities will be head, head, head, head, head, head, head, head, head, head, head, head, tail, and head, then triple head and tail, then head, tail, tail, tail, and head.

Head, head, tail, tail, tail, tail, tail, head, tail, tail, head, tail, tail, head and head, then tail, head, head, tail, tail, tail, tail, tail, triple tail, head, head, tail, tail, tail, tail, tail, tail, tail, tail, then tail, tail, tail, tail, tail, tail, then triple, tail, head, head, tail, head, head, head, head, head, head, head, head, and all the four are tails then tail triple head and finally tail double head and tail these are the 16 possibilities of the outcome now the probability of a that is head is flipped first how many times this occur that means head alone first occurs that is one two three four five seven and eight so it is eight divided by sixteen which is nothing but one divided by two the next one will be probability of b which is nothing but exactly two hits exactly two heads and two tails so exactly exactly exactly two heads and two tails means it is one then two three four five six seven seven times it is exactly two heads and two tails so it won't come here this won't come so exactly two heads one two and 6, right? so it is 6 times.

Therefore, 6 divided by 16, which is equal to 3 by 8...
