Answer:
1/8
Step-by-step explanation:
To find the probability of two events happening we need to find the probability of each event happening first:
For the spinner there are 8 possibilites (landing 1, 2, 3...8) and we are looking for factors of 3 which are 1 and 3 (3 is prime) therefore:
The chance of landing a factor of 3 on the spinner is 2/8=1/4
For the head there are two possibilities (heads and tails) and only one event we want happening (heads), therefore:
The chance of landing on heads on a fair coin is 1/2
Now to find the chances of both events happening we must multiply them to find that:
(1/2) ⋅ (1/4) = 1/8 the chances of the event happening
