Choose the incorrect statement.
If a card is picked at random from cards numbered 1 to 16, then:

1. the probability that the drawn card bears a number which is a factor of 16 is $\Big(\dfrac{1}{4}\Big)$

2. the probability that the drawn card bears an odd composite number is $\Big(\dfrac{1}{8}\Big)$

3. the probability that the drawn card bears a number which is a multiple of both 2 and 3 is $\Big(\dfrac{1}{8}\Big)$

4. the probability that the drawn card bears a number which is both a perfect square and a perfect cube is $\Big(\dfrac{1}{16}\Big)$

S = {1, 2, 3, ….., 16}, where the total number of outcomes is 16.

Let E be the event of getting a card with number that divide 16 perfectly, then

E = {1, 2, 4, 8, 16}

The number of favorable outcomes to the event E = 5

∴ P(E) = $\dfrac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} = \dfrac{5}{16}$

The probability that the drawn card bears a number which is a factor of 16 is $\Big(\dfrac{1}{4}\Big)$ is incorrect.

Hence, option 1 is the correct option.
