Answer:
[tex]\frac{3}{12}[/tex]
Step-by-step explanation:
There are two things that can happen when you flip a coin (it lands on either heads or tails), therefore:
The probability it lands heads-up is [tex]\frac{1}{2}[/tex]
There are six things that can happen when you roll a 6-sided die, therefore:
The probability it rolls 1-3 = [tex]\frac{3}{6}[/tex]
To find the probability of both of these things happening, you multiply the fractions together, by multiplying together the denominators an numerators:
[tex]\frac{1}{2}[/tex] × [tex]\frac{3}{6}[/tex] = [tex]\frac{3}{12}[/tex]
