Kim rolls a dice and flips a coin.

For coin: we have either H or T  

For dice: we have 1, 2, 3, 4, 5 or 6

On a coin, the probability of heads:  [tex]\frac{1}{2}[/tex]

On a dice, the probability of getting 2 : [tex]\frac{1}{6}[/tex]

Hence, the probability of getting a 2 and a head is

[tex]\frac{1}{2}\times\frac{1}{6}[/tex] = [tex]\frac{1}{12}[/tex]

So, the probability that Kim gets a 2 and a head is [tex]\frac{1}{12}[/tex]
