Answer» given that Cards NUMBERED 2 to 101 are placed in a box. So, total no. of cards = 100Now we are supposed to find the PROBABILITY that the card selected has a NUMBER which is a perfect square.So, perfect squares between 2 and 101 are {4,9,16,25,36,49,64,81,100} No. of cards of perfect squares = 9Total no. of cards = 100So, probability of getting a number which is a perfect square.= 9/100hope it helps you |
