In a race brian collins has to cross 10 hurdles. find the probability that he jumps a hurdle is 2/3. find p(knocks down all hurdles)

 Option 'a' is correct.

Step-by-step explanation:

Since we have given that

Probability that he jumps a hurdle =

Total number of hurdles = 10

Probability that he knocks down =

So, Probability (knocks down all hurdles ) is given by

Hence, Option 'a' is correct.

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
