A) A fair coins is tossed 5 times. what is the probability tat it lands on heads exactly once?round you answer to two decimal places

Answer :

The possible outcomes are; HTTTT or THTTT or TTHTT or TTTHT or TTTTH

Prob(H) = 1/2 and Prob(T) = 1/2

Prob(exactly one head) = 5 x Prob(HTTTT)

[tex]=5\times(\frac{1}{2})^5=\frac{5}{2^5}=\frac{5}{32}=0.15625\approx0.16[/tex]
