One ticket is drawn at random from a bag containing tickets numbered 1 to 40. The probability that the selected ticket has a number which is a multiple of 5 is

1. $\dfrac{1}{5}$

2. $\dfrac{3}{5}$

3. $\dfrac{4}{5}$

4. $\dfrac{1}{3}$

If a number is randomly chosen from the numbers 1, 2, 3, 4, …….., 25, then probability of the number to be prime is

1. $\dfrac{7}{25}$

2. $\dfrac{9}{25}$

3. $\dfrac{11}{25}$

4. $\dfrac{13}{25}$

If a (fair) coin is tossed twice, then the probability of getting two heads is

1. $\dfrac{1}{4}$

2. $\dfrac{1}{2}$

3. $\dfrac{3}{4}$

4. 0

If two coins are tossed simultaneously, then the probability of getting atleast one head is

1. $\dfrac{1}{4}$

2. $\dfrac{1}{2}$

3. $\dfrac{3}{4}$

4. 1
