Answer 1

Step-by-step explanation:

i) The total number of cards are 101. The square numbers between 10 and 110 are 16, 25, 36, 49, 64, 81 and 100. So there are 7 numbers.

P(E) = 7/101.

ii) The multiples of 6 between 10 and 110 are 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96, 102 and 108. So there are 17 numbers.

P(E) = 17/101.
