Question 1:
Cards marked with numbers 2 to 101 are placed in a box and mixed thoroughly. One card is drawn from this box randomly, then the probability that the number on card is a perfect square. A. 9/100
B. 1/10
Feedback The perfect square numbers between 2 to 101 are:
1, 4, 9, 16, 25, 36, 49, 64, 81, 100
So probability of getting a card with perfect square number is:
P (perfect square) = 10/100 =1/10
1, 4, 9, 16, 25, 36, 49, 64, 81, 100
So probability of getting a card with perfect square number is:
P (perfect square) = 10/100 =1/10
C. 3/10
D. 19/100
