Question

8 coins are tossed what is the probability of getting one and only turns up head?

Answer 1

Answer:

1/32

Step-by-step explanation:

Let S be the sample space,

therefore,

n(S) = 2⁸ = 256 possibilities

Let A be event that coins tossed gives one and only Head.

n(A ) = 8 possibilities

therefore, P(A) = n(A) / n(S)  ==> 8/256

Therefore the probability of the given event is ==> 8/256 = 1/32
