Question

A die is thrown 6 times. If ‘getting an odd number’ is a success, what is the probability of (i) 5 successes? (ii) at least 5 successes? (iii) at most 5 successes? Select the correct answer from above options

Answer 1

There are 3 odd numbers on a die ∴ Probability of getting an odd number on a die = 3 6 = 1 2 (i) Probability of getting 5 success P(5) = 6C5 (ii) Probability of getting at least 5 successes P(at least 5 success) = P(x = 5) + p(x = 6)
