Question

16. If a die is rolled 4 times, what is the probability that 6 comes up at least once?

Answer 1

probability = no. of favourable conditions ÷ no. of possible outcomes
no. of favourable conditions = 4
no. of possible outcome = 4.
so therefore probability = 4÷4 = 1.
probability = 1

Answer 2

sample space {1,2,3,4,5,6}
probability of getting 6 at the top=number of favourable outcome/ total number of outcomes
number of getting 6at the top=1
total number of outcomes=6
hence the answer is 1/6
