Aspinner has three equal sections labeled 1, 2, and 3. it is spun twice. which expression can be used to determine p(2, then 1)?

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) =

                                                         =
