Question

Spin a spinner numbered 1 to 5 and toss a coin. What is the probability of spinning an odd number

and getting tails on the coin?
a) 2/5
B)3/10
C)4/5
D)None of the above

Answer 1

B 3/10 because you just half it

Answer 2

Answer: B
`(3)/(10)`

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.

`(Odd Numbers)/(Total Numbers)` =
`(3)/(5)` = 0.6

3. Do the same for the coin

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

`(Tails Side)/(Total Sides)` =
`(1)/(2)` = 0.5

4. Multiply the two decimals together

0.5 x 0.6 = 0.3

5. Convert to fraction

0.3 →
`(3)/(10)`
