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

The correct answer is B. 3/10.

Step-by-step explanation:

1. Let's calculate the probability of spinning an odd number:

We can spin an odd number (1, 3 or 5) out of 5 events, it means that the probability of spinning an odd number is:

3/5

2. Let's calculate the probability of getting tails on the coin:

We can toss a coin and get tails one out of 2 events, it means that the probability of getting tails on the coin is:

1/2

3. These are independent events because the fact that we spin an odd number does not affect the probability of getting tails on the coin, thus:

Probability of spinning an odd number and getting tails on the coin =

3/5 * 1/2 = 3/10

The correct answer is B. 3/10
