a. S_1 = \{1,2,3,4,5,6\}

b. S_2=\{A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z\}

c. S_3 = \{HH, HT, TH, TT\}

d. S_4 =\{1T,2T,3T,4T,5T,6T,1H,2H,3H,4H,5H,6H\}

Step-by-step explanation:

We will write the sample space of all options one by one.

<u>a. Rolling a 6 sided die</u>

As the die has six sides numbered from 1 to six then the sample space will be:

S_1 = \{1,2,3,4,5,6\}

<u>b. Guessing the first initial of a student's name:</u>

As the English language has 26 alphabets, the first initial can be any alphabet so the sample space will be all letters:

S_2=\{A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z\}

<u></u>

<u>c. Tossing two coins</u>

As two coins are tossed, the outcomes will be a combination of two outcomes

S_3 = \{HH, HT, TH, TT\}

<u>d. Rolling a 6 sided die and tossing a coin</u>

As the die is rolled and then a coin is tossed. The die's coin will either combine with heads or tails

So,

S_4 =\{1T,2T,3T,4T,5T,6T,1H,2H,3H,4H,5H,6H\}

Hence,

a. S_1 = \{1,2,3,4,5,6\}

b. S_2=\{A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z\}

c. S_3 = \{HH, HT, TH, TT\}

d. S_4 =\{1T,2T,3T,4T,5T,6T,1H,2H,3H,4H,5H,6H\}
