Question

cards with number 2 to 101 are placed in a box. a card is selected a random . find the probability that the card has a square number

Answer 1

there are 9 squares b/w 2 and 101. (4,16,25,36,49,56,81,100)

Hence the probability will be 9/99=1/11

Answer 2

Answer:

The answer should be 9/100 (because you are including 2 in 101)

Step-by-step explanation:

Since there are 9 types of squared number

P(even): {2,3,4,5,6,7,8,9,10}

(if you squared them) {4,9,16,25,36,49,64,81,100}

and you know that it starts from 2 to 101, so 1 is missing out, so the 101 will change to 100 (because 1 is not included)

So, only thing you have to do is:

The probability of (even): {2,3,4,5,6,7,8,9,10}

divide by

The total outcomes: 100 cards
