Choosing a day of the week

Answer

S: {Sunday, S: {Sunday, Monday,Tuesday, Wednesday, Thursday, Friday, Saturday}

n(S)=7

Probability of event A occurs

= Number of times event A occursNumber of trials

P(A)=n(A)n(S)

1 6 9 16 24 36Siti puts the above six cards in a box. If Siti puts the above six cards in a box. If Siti picks a card randomly from the box, find the probability of obtaining a) a odd numberb) A number less than 15

Let S the sample space , S={1,6, 9,16,24,36}

n(S)=6

a) Let K be the event of picking an odd number

K={1,9}K={1,9}

P(K)=n(K)

n(S)

=2

b) Let T be the event of picking a number less than 15

T={1,6,9}

P(T)= n(T)

n(S)n(S)

�The probability of the vowel is chosen from the word is chosen from the word EXAMINATION

Let S the sample space , S={E,X,A,M,I,N,A,T,I,O,N}

n(S)=11

a) Let V be the event of vowel is choosena) Let V be the event of vowel is choosen

V={E,A,I,A,I,O} n(V)=6

P(V)=n(V)

n(S)

� State the compliment of getting a vowel from the getting a vowel from the word “EXCELLENT”

Sample Space ={E,X,C,E,L,L,E,N,T}

n(S)=9the vowel ={E,E,E}the vowel ={E,E,E}n(vowel)=3P(vowel)=3

9=13

P(Not getting the vowel)

= 1-1
