Question 443137: Since I can't include the pictures of the circles/spinners, I will describe them below:
Fig 12.16 Circle is one half red and one half yellow.

Fig 12.17 Circle is one half green, one quarter red and one quarter yellow.
TWO SPINS: Assume that the pointer in Fig. 12.16 is spun and then the pointer in Fig. 12.17 is spun. Determine the probability of the pointers landing on yellow on the first spin and red on the second spin.

Fig 12.16 Circle is one half red and one half yellow.

Fig 12.17 Circle is one half green, one quarter red and one quarter yellow.
TWO SPINS: Assume that the pointer in Fig. 12.16 is spun and then the pointer in Fig. 12.17 is spun. Determine the probability of the pointers landing on yellow on the first spin and red on the second spin.
------------
The spin results are independent events.
---
In Fig 12.16 one-half is yellow so P(yellow) = 1/2
In Fig 12.17 one-quarter is red so P(red) = 1/4
----
Since the results are independent,
P(yellow then red) = (1/2)(1/4) = 1/8
