Answer:

[tex]\dfrac{1}{4}[/tex]

Step-by-step explanation:

The sample space of rolling a six-sided die and a coin is given below:

[tex]\left|\begin{array}{c|ccccccc}&1&2&3&4&5&6\\--&--&--&--&--&--&--\\H&H1&H2&H3&H4&H5&H6\\T&T1&T2&T3&T4&T5&T6\end{array}\right|[/tex]

Total Number of Possible Outcomes = 12, i.e. n(S)=12

Let the event of getting a head  followed by an even number = A

A={H2, H4, H6}

n(A)=3

Therefore:

Probability of getting a head  followed by an even number

[tex]=\dfrac{n(A)}{n(S)}\\ =\dfrac{3}{12}\\\\=\dfrac{1}{4}[/tex]
