Question

Cards each marked with
one of the numbers 6 to
50 are placed in a box
and mixed thoroughly.
One card is drawn at
random from the box.
Find the probability of a
number which is a perfect
square.​

Answer 1

Answer: 1/9

Step-by-step explanation: 6 + (n-1) = 50 where n is the number of values

or there are 45 values.

Perfect squares from 6 to 50 - 9, 16, 25, 36, 49 or 5 values.

So probabilty of picking one of these five values from a box with all 45 values = 5/45 = 1/9 (ans.)
