Answer:
Probability of nickle getting a head: 1/2
Probability of a dice rolling to a four: 1/6
Step-by-step explanation:
Since a nickle has two sides, getting a head would be one in two sides. (1/2)
Since a dice has 6 numbers, rolling a four would be one in six numbers. (1/6)
To have the probability of both of them happening: simply multiply 1/2 and 1/6 (1/12)
