on the spinner what is the probability of spinning a number greater than 2? this picture goes to this

1/2
5/8
3/8
1/4

2.you write each letter of the work mathematician on a piece of paper and put them in bag. you randomly select one piece from the bag what is p(t or a)

5/13
5/8
1/3
8/13

3.you have 3 pairs of white socks 4 pairs of black socks and 2 pairs of colored socks in your drawer what is the probability that you reach into the drawer and randomly select a pair of white socks?

1/2
1/3
2/3
3/7

1.

a. With the picture missing, and 8 appearing in the choices, a can only assume that the spinner has 8 equal sectors. 

b. P(Event)=n(Event)/n(Sample space)

c. P(number greater than 2)=n{3,4,5,6,7,8}/n{1,2,3,4,5,6,7,8}=6/8=3/4

2. 

a. Sample Space: {2I, 3A, 2M, 2T, H, E, C, N}, n(S)=13

Event T:"selecting T" has a probability of P(T)=n(T)/n(S)=2/13
Event A: "selecting A" has a probability of P(A)=n(3)/n(S)=3/13

Events A and T are mutually exclusive, so P(A or T)=P(A)+P(t)=5/13

3. 

a. Event W: white socks, n(W)=3

b. n(Sample space)=n(S)=n(3W, 4B, 2C)=9

c. P(W)=n(W)/n(S)=3/9=1/3
