Answer:
1024/59049
Step-by-step explanation:
P( clear hurdle) = 2/3
There are 10 hurdles
P ( clear all hurdles) = P( clear hurdle) * P( clear hurdle)...... 10 times
= 2/3 * 2/3 *....... 10 times
= (2/3) ^ 10
=1024/59049
Its 8 because your not adding your subtracting.
of means times so you multiply the fractions
1 x 9 = 9
3 x 16 = 48 (we multiplied numerators and denominators)
9/48 = 3/16 (Simplify by dividing a multiple on both the numerator and denominator
