and getting tails on the coin?

B)3/10
C)4/5
D)None of the above

Respuesta :

Answer: B [tex]\frac{3}{10}[/tex]

Step-by-step explanation:

1. Count the possible odd numbers from 1-5 compared to the even ones

1, 3, 5 (3 out of 5 numbers)

2. Calculate the chance for landing on an odd number.

[tex]\frac{Odd Numbers}{Total Numbers}[/tex] = [tex]\frac{3}{5}[/tex] = 0.6

3. Do the same for the coin

2 possible sides, 1 of them being TAILS (1 out of 2 sides)

[tex]\frac{Tails Side}{Total Sides}[/tex] = [tex]\frac{1}{2}[/tex] = 0.5

4. Multiply the two decimals together

0.5 x 0.6 = 0.3

5. Convert to fraction

0.3 → [tex]\frac{3}{10}[/tex]

B 3/10 because you just half it
