A box contain cards no 11to23 .a card is drawn at randimfrom the box.

1.	A box contain cards no 11to23 .a card is drawn at randimfrom the box. find the probability that the numberon the drawn cardsis (1)a square of no (2)a multiple of7
Answer» find out the total no. of elements in total between 11 and 23. it is , 12 elements . now for the first part let us find out the no. which are squares . There is only 16 which is a square of 4 . THEREFORE the PROBABILITY will be total no. of square no. i.e 1 upon total no. of elements i.e. 12 therefore probability for FINDING a square no . is 1/12 similarly , the multiple of SEVEN between 11 and 23 are 14,21 . there fore probability will be 2/12 . hope it helped ,.

THEREFORE the PROBABILITY will be total no. of square no. i.e 1 upon total no. of elements i.e. 12 therefore probability for FINDING a square no . is 1/12

similarly , the multiple of SEVEN between 11 and 23 are 14,21 . there fore probability will be 2/12 .

hope it helped ,.
