Question

If a coin is tossed 6 times, then the probability of getting exactly 1 head is ..

Answer 1

Total number of possible outcomes = 2 (That is, head or tail)

P(head) = 1/2

P(tail) = 1/2

P(exactly 1 head in 6 throws) = 6 [ P(head)¹ x P(Tail)⁵ ]

P(exactly 1 head in 6 throws) = 6 [ (1/2) x (1/2)⁵ ]

P(exactly 1 head in 6 throws) = 6 [ 1/64 ]

P(exactly 1 head in 6 throws) = 3/32

Answer: The probability of getting exactly 1 head in 6 throws in 3/32
