Question

Cameron writes down one letter from the word 'HOUR".
Then he writes down one number from 5, 6 and 7
List all the possible combinations Cameron can write down​

Answer 1

Answer

Sample space -{H,O,U,R}

n(s)=4

Event A : One letter written by cameron (assuming H)

A={H}

n(A)= 1

therefore the possibility of Cameron writing letter H is 1/4 (acc to assumption )

Number written by cameron

S={5,6,7}

n(s) = 3

Event A : Number written by cameron (assuming 7)

A= {7}

n(A) = 1

therefore the possibility of Cameron writing a number 7 is 1/3 (according to assumption)

--------(formula i used here and the above is the formula of removing Probability )i.e P(A) = n(A)/n(S)
