Question

there are two 2 to 49 tickets find probability of prime ticket and multiple of 3 or 7​

Answer 1

Answer:

Let S be the sample space

S={2,3,4,5...........48,49}

therefore n(S)= 48

Event A :

A={ 3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48}

therefore n(A)= 16

p(A)=n(A)/n(S)= 16/48=1/3

Event B:

B={ 7,14,21,28,35,42}

therefore n(B)=6

p(B)= n(B)/n(S) = 6/48=1/8
