Step-by-step explanation:
Given :A spinner has three equal sections labeled 1, 2, and 3. It is spun twice.
Solution :Which expression can be used to determine P(2, then 1)?
Solution :
Total no. of events = {1,2,3}=3
When it is spin for the first time .
Since we are given in the first spin she should get 2
No. of Favorable events ={2}=1
probability of getting 2 =
= 1/3
In second spin she should get 1
No. of Favorable events ={1}=1
probability of getting 1=
=
Thus P(2, then 1) =
Hence the expression : P(2, then 1) =
=

Finding the equivalent multiplier, it is found that the function for the final price is:
P(x) = 0.68x.
-------------------------------------------
- There is a holiday sale of 20% off the price of x, thus 0.8x is paid, as 1 - 0.2 = 0.8.
- Additionally, there is a coupon of 15% off, thus, 0.85 of 0.8x is paid.
- The equivalent multiplier is:
- Thus, the function for the final price is:
